Top 50 Critically Endangered Animals in the Philippines

In my childhood, I adopted a puppy that changed my life and attitude towards animals. I have since become a lifelong animal lover.

Read on to learn about some of the most endangered species in the Philippines, including the Philippine eagle, pictured above.

Read on to learn about some of the most endangered species in the Philippines, including the Philippine eagle, pictured above.

A wide variety of the planet's animal species call the Philippines home. Conservation International, a nonprofit environmentalist group founded in 1987, recognizes the Philippines as one of only 17 mega-diverse countries worldwide. Mega-diverse countries are nations that shelter the bulk of Earth's animal and plant life. In other words, these countries have extreme biodiversity in terms of genetic, genus, and bio-network mixtures.

With so much biological diversity, the country is also home to many threatened animal species. As of the day this article was published, the International Union for the Conservation of Nature and Natural Resources (IUCN) had declared 418 animal species in the Philippines to be threatened: meaning they are either vulnerable, endangered, or critically endangered, according to the IUCN red list criteria.

This article lists the top 50 critically endangered animals in the Philippines:

Philippine Eagle (Pithecophaga jefferyi)

Philippine Eagle (Pithecophaga jefferyi)

1. Philippine Eagle (Pithecophaga jefferyi)

Also called the monkey-eating eagle, the Philippine eagle is native to the southern Philippines. It is characterized by a brown and white feather pattern and bushy crest and is believed to be one of the largest and most powerful birds on Earth. A full-grown adult can grow to as big as four feet (ft) tall and can weigh as much as nine kilograms (kg). The monkey-eating eagle is the Philippines' national bird. Deforestation, mining, and pollution are major threats to the Philippine eagle's survival.

Conservation Rationale
Due to several factors, the IUCN has the Philippine eagle on its red list of critically endangered animals. In 1988, it was added to the list of animals in threat of extinction. In the1990s, it was classified as critically endangered.

There are very few of these eagles left. Their global population has been steadily declining for the past 56 years. Various legislations have been passed protecting the Philippine eagle, but such laws have been poorly enforced, thus the continued decline in the eagle's numbers.

There are natural reserves and other protected areas at natural parks like Mt. Apo and Mt. Katinglad. The Philippine Eagle Center, which can be found in Davao on the island of Mindanao, oversees the captive breeding of these eagles.

Philippine Freshwater Crocodile (Crocodylus mindorensis)

Philippine Freshwater Crocodile (Crocodylus mindorensis)

2. Philippine Freshwater Crocodile (Crocodylus mindorensis)

Locally known as Mindoro crocodiles, they are endemic in the Philippines. The Philippine freshwater crocodile is quite small compared to other crocodiles, growing to about four and a half to five feet long and weighing approximately 15 kg. The Mindoro crocodile is also listed as critically endangered by the IUCN. It is reported that as of September 2011, only 250 of them are left in the country. Experts attribute illegal hunting and dynamite fishing to the decline of the Philippine freshwater crocodile.

Conservation Rationale
The Philippine freshwater crocodile is currently on the IUCN red list and is classified as a critically endangered species. Population trend estimates say that the number of this specie is continuing to decline. One of the threats to this species includes excessive exploitation for commercial use, but the biggest threat it faces to date is the massive clearing of rainforests that serve as the crocodile's natural habitat. The forests are cleared to be converted into farmlands.

Another threat comes from the locals themselves, who illegally hunt the crocodiles. There is a current need to educate locals on the difference between the small Philippine freshwater crocodile and the saltwater crocodiles that also inhabit the same area. Locals tend to hunt the smaller and endangered local crocodile species without realizing the damage they are causing.

Tamaraw (Bubalus mindorensis)

3. Tamaraw (Bubalus mindorensis)

Also known as the Mindoro dwarf buffalo, the Tamaraw is the only known bovine indigenous to the Philippines. Until the 20th century, the original habitat of this species was essentially intact and unharmed. They were once found all over Mindoro Island, from the plains up to the mountains. But now, the population has been reduced to about 200, with many being carefully bred in captivity.

Another critically endangered animal, according to the IUCN, the main causes of the Tamaraw being on the list of endangered animals in the Philippines are illegal hunting, logging, and residential land clearing.

Distinguishing Features
The Tamaraw shares a lot of physical traits with other types of bovine. It has a heavyset body, legs that end in cloven hooves, a short neck, and a horned head. However, unlike the other species in its family, this one tends to be smaller and much stockier. Males have thicker necks compared to females.

It has an average shoulder height of 39 to 41 inches (in) and can grow up to 7.2 feet in length. The heaviest Tamaraw ever recorded weighed around 660 pounds (lbs).

Adult Tamaraws have a darker grey or brown color. They have distinctly shorter legs compared to other buffalo species. Their inner lower forelegs, as well as their hooves, have distinct white markings. The ears also exhibit the same white markings on the tips.

Walden's Hornbill (Aceros waldeni)

Walden's Hornbill (Aceros waldeni)

4. Walden's Hornbill (Aceros waldeni)

Locally called a Kalaw, it is also known as the Visayan Wrinkled Hornbill. The Kalaw is endemic to the Philippine islands of Panay and Negros. However, it can also be found in other regions of the country, such as Zamboanga del Norte in Mindanao. Excessive hunting and illegal logging caused the disappearance of this species in the areas of Negros and Guimaras. Because of that, it has been included in the IUCN Red List of critically endangered species in the country.

Distinguishing Features
This colorful bird is also the world's second most critically endangered species of hornbill. Like other species in its family, Walden's hornbill also has that distinct bony casque atop its bill. The Walden hornbill, however, has a reddish-orange colored casque that looks wrinkled.

Other than the reddish-orange bill, it also has a distinctly ridged mandible. The feathers on the upper chest, as well as the necks, are reddish-orange colored as well. Another distinct feature is the bare skin around its red eyes.

The plumage on its body is usually black, but its tail feathers are white with a black tip. Female Kalaws are smaller than males. The feathers on their breast, neck, and head are black. Females are also brown-eyed with a blue-green coloration on the skin.

Visayan Warty Pig (Sus cebifrons)

Visayan Warty Pig (Sus cebifrons)

5. Visayan Warty Pig (Sus cebifrons)

This land mammal is also on the IUCN's list of critically endangered species in the Philippines. Once ubiquitous in the central Philippines, especially on the island of Cebu, the pig can now only be found on two islands: Panay and Negros. Some experts believe that a small herd may still be located on the island of Masbate, although it is not confirmed.

The disappearance of this species on the island of Cebu was brought about by illegal hunting and logging and agricultural land clearing. The animal's natural habitats were turned into rice fields to accommodate the growing demand for crops in the region. Now, small population concentrations of this species are bred in captivity. Some still live in the wild, although they are very rare, which is why not much is understood about the mammal's natural behavior.

Distinguishing Features
This species is also known by a variety of names among the locals. It is called the Cebu bearded pig, Baboy Talunon, Bakatin, and Baboy Ilahas, among others. Adult Visayan Warty Pigs can grow up to 100 centimeters (cm) in length. Females can have a maximum shoulder height of 45 cm, while males grow up to 63 cm. Its longest tail length is around 23 cm. Adult females weigh between 20 and 35 kg while adult males weigh between 35 and 40 kg. Estimates show that the largest adults of this species can weigh up to 80 kg.

The body of this mammal is covered, albeit sparsely, with bristly hairs. The hairs are usually dark grey for males and light brown or silvery for females. The males, especially those found on Panay Island, grow tufts of hair from their heads down to their necks, which eventually become manes. The most distinguishing feature of this species is the white stripe that runs along the bridge of their noses all the way to their mouths.

Philippine Cockatoo (Cacatua haematuropygia)

Philippine Cockatoo (Cacatua haematuropygia)

6. Philippine Cockatoo (Cacatua haematuropygia)

Locally known as Kalangay, Katala or the red-vented cockatoo, the Philippine cockatoo is indigenous to the Philippines. This species used to be common in the whole country, but today only 180 of them are known to live in the wild within the forests of Palawan.

The IUCN lists these birds as critically endangered because of illegal trapping by poachers hoping to profit from selling them to private collectors and pet enthusiasts. Another reason for the population decline is that the birds are considered agricultural pests and are killed or trapped by farmers attempting to protect their fields.

Distinguishing Features
The Philippine cockatoo is covered in white plumage, which makes it really attractive. However, the bird's undertail coverts are red with white tips. The feathers under its wings are pale yellowish. It also has the ability to mimic the human voice, which makes it a highly valued pet. This is why it is vulnerable to the illegal wildlife trade.

Negros Bleeding-Heart (Gallicolumba keayi)

Negros Bleeding-Heart (Gallicolumba keayi)

7. Negros Bleeding-heart (Gallicolumba keayi)

This type of pigeon is endemic to the islands of Negros and Panay in the Philippines and is one of the many critically endangered pigeon species in the country listed by the IUCN. These birds always come in pairs or a flock and are ground feeders, meaning they hunt on the ground and are easy pickings for poachers. Its population continues to decrease because of ongoing deforestation, excessive hunting for its meat and the exotic pet black market.

Distinguishing Features
The Negros bleeding-heart is a very colorful bird. It is medium-sized and grows up to 30 cm tall. It is a ground-dwelling pigeon that has a characteristically short tail. Its name, "bleeding heart," comes from the bright narrow line of red feathers enveloped by white feathers at its chest and throat.

To add to its vivid array of colors is a mantle of iridescent green that covers its crown, lesser wing coverts, nape, breast sides, and upper mantle. This forms an incomplete breast band. Its inner wing coverts have a greyish-white band of feathers. The feathers on its belly feathers have a creamy white color.

Philippine Naked-Backed Fruit Bat (Dobsomia chapmani)

Philippine Naked-Backed Fruit Bat (Dobsomia chapmani)

8. Philippine Naked-backed Fruit Bat (Dobsomia chapmani)

Also called the Philippine bare-backed fruit bat, these are large bats found in the caves of Negros Island in the Philippines. They are listed as critically endangered by the IUCN, and a small population is reported to have been sighted on the island of Cebu as well.

Deforestation and agricultural land clearing are the main causes of their population and habitat reduction. In the 1980s, locals cut down lowland forests in favor of sugar cane plantations, and the bats gradually disappeared afterwards. In 1996, the IUCN proclaimed that the species was extinct but revoked the classification in 2000 when a small group was sighted.

Distinguishing Features
The Philippine naked-backed fruit bat is one of the species of mega-bat that are endemic to the country. Most of its population lives on the island of Negros. Like all species of fruit bats with a bare back, its wings meet along the midline of its body. It is surprisingly agile when it flies across the sky.

An adult Dobsomia chapmani will measure anywhere from 218 mm to 221 mm in length, from the tip of its notes to its tail. They usually weigh from 125 to 143 grams. The connection of the wings to their back's midline gives it a furless appearance.

Philippine Forest Turtle (Siebenrockiella leytensis)

Philippine Forest Turtle (Siebenrockiella leytensis)

9. Philippine Forest Turtle (Siebenrockiella leytensis)

Also known as the Palawan turtle or Leyte pond turtle, this freshwater turtle is native to the Palawan islands of the Philippines. They are classified as critically endangered by the IUCN, and several conservation programs have been conducted to increase their population.

With its highly hostile territorial behavior, the Philippine forest turtle does not thrive naturally in captivity. Because of habitat loss and too much catching by collectors, they have dramatically decreased in numbers.

Distinguishing Features
The Philippine forest turtle is known by several other names, such as the Leyte pond turtle, the Palawan turtle, and the Philippine pond turtle. Even though some people call it the Leyte pond turtle, it is nonexistent on Leyte Island. This turtle species is, in fact, a native of the island of Palawan.

Its vertebral scutes have a rather ginkgo shape. It also has a gradation of pale-white to yellowish coloration line to be found near its ears. This is also the reason why some folks call it the bowtie turtle.

Dinagat Bushy-Tailed Cloud Rat (Crateromys australis)

Dinagat Bushy-Tailed Cloud Rat (Crateromys australis)

10. Dinagat Bushy-tailed Cloud Rat (Crateromys australis)

This type of cloud rat is indigenous to Dinagat Island in the Philippines. They are nocturnal by nature and are herbivores. They are one of several cloud rat species listed by IUCN as critically endangered in the country. They have almost been driven to extinction because of the loss of their natural homes due to deforestation, chromite mining, and excessive hunting. Cloud rat meat is considered a delicacy among the locals.

Distinguishing Features
The Dinagat cloud rat has a tail that is longer than the length of its body. The length of its tail is around 11 in or 28 cm. Its body is about 10.4 in (measuring from its nose to its rear, excluding the tail). It has a rather orange or tawny-colored fur. It does not bear color patterns on its body.

Its head does not have the familiar crest of fur present in other family members. It also has a characteristic striped tail. Its ears are heavily pigmented and round. Each ear also has short, brown hairs. Its lower parts have an orange-like shade beginning from the neck all the way down to its belly.

Hawksbill Sea Turtle (Eretmochelys imbricate)

Hawksbill Sea Turtle (Eretmochelys imbricate)

11. Hawksbill Sea Turtle (Eretmochelys imbricate)

This sea turtle is commonly known among the locals in the Philippines as the Pawikan. This turtle species can also be found in other parts of the world. The Hawksbill sea turtle shares many features with other types of marine turtle species.

Distinguishing Features
Like other turtles, it has a protective carapace that serves as its distinguishing feature. Unlike the typical land turtle, this marine turtle has a flattened body shape and limbs shaped like flippers for hydrodynamic efficiency when swimming.

Its most distinguishing feature is its Hawk's bill (hence its name): a narrow, pointed beak. Considered a medium-sized reptile, they can grow up to three feet in length and weigh up to 180 lbs. The heaviest recorded Hawksbill caught in the wild weighed around 280 lbs.

The turtle's shell is known for its amber coloration. It also has streaks of light and dark colors. You will find other shell colors, which include brown. The shell often appears to be speckled.

Hawksbills are vegetarian, and adults are usually found feeding in coral reef areas. They also nest and forage in mangroves. This is a migratory species of sea turtle. As such, they can thrive in various habitats such as mangrove swamps, lagoons, and even in the open ocean.

The Philippine Tarsier (Carlito syrichta)

The Philippine Tarsier (Carlito syrichta)

12. The Philippine Tarsier (Carlito syrichta)

This small primate is another endangered species endemic to the Philippine islands. This species was once widespread throughout Southeast Asia. Fossils of these animals were also found in North America and Europe. Tarsiers today can also be found in other Asian countries such as Indonesia and Malaysia.

In the Philippines, you can find tarsier in the southeastern region of the archipelago. Current data shows that species have been found inhabiting the islands of Mindanao, Samar, Bohol, and Leyte. Some can also be found on Maripipi Island, Dinagat Island, and Siargao Island.

Distinguishing Features
The Philippine tarsier is considered one of the smallest species of primates in the world. They measure around 118 to 149 millimeters (mm) and weigh somewhere from 113 to 142 grams. In contrast to their little bodies, tarsiers have distinctly large eyes. Their anatomy shows that a tarsier eyeball is as big as the animal's brain. A tarsier's eyeball can have a diameter of 16 mm.

Philippine Spotted Deer (Cervus alfredi)

Philippine Spotted Deer (Cervus alfredi)

13. Philippine Spotted Deer (Cervus alfredi)

The Philippine spotted deer is a nocturnal animal and one of the country's three endemic species of deer. They primarily thrive in the rainforests found in the islands of Negros and Panay. However, they used to be found in neighboring islands such as Samar, Masbate, Leyte, Guimaras, and Cebu.

Distinguishing Features
This species of deer is comparatively small with its short legs. Nevertheless, they are the biggest deer specimens in the country's Visayan Islands. An adult spotted deer can grow up to 51 inches in length and about 31 inches in height, measuring from the base of the foot to the shoulder. An adult deer can weigh as much as 85 kg.

Conservation efforts are ongoing as conservationists work to create reservation areas on various islands. However, despite such efforts, only an estimated 300 spotted deers are still in the wild. Local wildlife groups and conservationists are poorly funded and face very little support from the government.

Sulu Hornbill (Anthracoceros montani)

Sulu Hornbill (Anthracoceros montani)

14. Sulu Hornbill (Anthracoceros montani)

To date, studies have shown that the Sulu hornbill now faces the imminent danger of extinction. It is believed to live only on one island in the Philippines, and its numbers are declining. The massive decline in the population of this species is caused by hunting, illegal wildlife trade, and the destruction of the forest tracts where this hornbill thrives.

Distinguishing Features
Dark black feathers cover the majority of the hornbill's body. In contrast, the tail feathers are white. A top coat of feathers on its upper parts is dark green and glossy, covering part of the wings and the back. The bird's bill and the skin around its eyes are black.

Male Sulu hornbills have cream-colored irises, while females have dark brown. Juvenile hornbills of this species either have white-tipped primaries or casque-less bills. These birds make shrieking and cackling calls in patterned intervals.

Negros Fruit Dove (Ptilinopus arcanus)

Negros Fruit Dove (Ptilinopus arcanus)

15. Negros Fruit Dove (Ptilinopus arcanus)

Because no recorded sighting of the Negros fruit dove has been made since the first specimen of the Negros fruit dove was collected in 1953, the IUCN put this bird on their red list. There was an unconfirmed report of a sighting in 2002 and other protracted surveys, but none of them can be confirmed.

This species of fruit dove is extremely shy, fleeing and hiding from surveyors. That being said, more surveys must be done on Panay Island, where the bird is believed to thrive. The main factors contributing to this bird species' decline include hunting and the destruction of its natural habitat.

Distinguishing Features
The existence of the Negros fruit dove is confirmed by only a single specimen—a female collected in the 50s. It is about 16.5 cm in length, which makes it very small. Its feathers are dark green, providing perfect cover in foliage. Another distinguishing feature is the ring of feathers around its eye, which are bright yellow.

It is also distinctly marked by a greyish-white coloration along its throat. It also has yellow feathers in the undertail coverts. Yellow fringes and dark streaks make a conspicuous feature on its folded wings.

16. Flame-breasted Fruit Dove (Ptilinopus marchei)

The IUCN classifies the Luzon Island endemic Flame-breasted fruit dove as vulnerable. The rapid decline of the island's forest has greatly contributed to the rapid decline of this bird's population. The other factors that contributed to the rapid population decline include hunting and illegal wildlife trade.

Distinguishing Features
This fruit dove is particularly large compared to other local species at 40 cm in length. The feathers on its head are peculiarly rusty red. A black patch of feathers marks its ear coverts. Another orange patch of feathers can be found extending from its throat to its under parts.

The feathers on its sides are markedly light grey. The feathers on its wings and back are chiefly black in color. The rump and tail have dark green feathers. It also has a red bill, and its legs are also reddish.

Giant Clams (Hippopus hippopus)

Giant Clams (Hippopus hippopus)

17. Giant Clams (Hippopus hippopus)

Hippopus hippopus is known by many different names. Some call it the Strawberry clam, Bear Paw, and also the Horse's Hoof. This species belongs to a family of large saltwater clams, specifically the giant clam family, which is why the locals just call it the giant clam. According to the IUCN, its conservation status is "conservation dependent," which is why it is included in the red list of threatened species.

Distinguishing Features
The shell of this type of clam is pretty hard and quite thick. The ribs are rather prominent. What makes it quite distinct from other clam species in its immediate environment are the reddish blotches you will find on its shell. Note that its mantle will hardly get past the edge of its shell. The mantle has a distinct brownish-green color with faint gold stripes. Another distinction is the absence of tentacles in the incurrent aperture, which are usually present in the members of the Tridacnidae family.

Cebu Flowerpecker (Dicaeum quadricolor)

Cebu Flowerpecker (Dicaeum quadricolor)

18. Cebu Flowerpecker (Dicaeum quadricolor)

Experts thought the Cebu flowerpecker had gone instinct in the early 20th century. This belief was largely due to the destruction of almost all of the island's forests. The good news is that it was rediscovered back in 1992. Today, the Cebu flowerpecker can be found within the Central Cebu Protected Landscape and in three other sites.

Note that despite conservation efforts, the population of this bird species is still extremely small. They have a severely fragmented range. The IUCN classifies this species as critically endangered.

Distinguishing Features
This flowerpecker species is rather short and stocky at 11 to 12 cm in length. The male birds of this species have a black head with many bright red feathers on their mantle and back. It also has dark blue wings and the same color combination for its tail. Males also have yellowish-green-colored feathers at their tails and rump.

Female species have rather dull-colored feathers though they exhibit the same patterns seen on males. They also have dark grey feathers on their backs. Unlike their male counterparts, females do not have a scarlet mantle of feathers on their backs.

Golden-Capped Fruit Bat (Acerodon jubatus)

Golden-Capped Fruit Bat (Acerodon jubatus)

19. Golden-capped Fruit Bat (Acerodon jubatus)

This species of mega-bat is also known as the Giant golden-crowned flying fox, one of the world's biggest bat species. The IUCN has placed it on the red list as an endangered species that is facing the possibility of extinction.

Forest destruction and illegal poaching have contributed to this bat's rapid decline. This bat is especially susceptible to population decline because of its reliance on fig trees that exist only in mature old-growth forests.

Distinguishing Features
This bat is much larger than other local bat species: it has an average wingspan of 5.6 ft and an average weight of 2.6 lbs or 1.2 kg.

These bats are nonaggressive towards humans. However, handling them is not advisable and is a bit dangerous. They are known disease carriers, meaning you still need to get properly vaccinated even if you have to handle them.

These bats are called "golden-capped" because of the golden patch of fur around their head. That cap of gold stands out in contrast to the black of its body fur.

Net Coral (Alveopora excelsa)

Net Coral (Alveopora excelsa)

20. Net Coral (Alveopora excelsa)

Alveopora excelsa populations are in decline. Due to this population trend, it has been included on the IUCN red list as an endangered species.

The current aquarium trade has made this specific type of coral a target, with its appearance making it an attractive addition to an aquarium. Other than extraction and use in aquariums, net corals are also susceptible to coral bleaching. Studies show that Alveopora excelsa have a high response to the bleaching phenomenon, making them a likely species to face immediate extinction.

Distinguishing Features
This coral usually forms colonies extending up to 2 meters (m). Their polyp skeleton usually has a pink color. When their tentacles have extended, the colonies eventually turn into a beautifully golden brown field. Because of their beautiful color, they're a popular pick for people collecting corals for aquariums.

21. Long Polyp Green (Alveopora minuta)

Even though this species is relatively widespread, it remains rare. In fact, sightings today are few and far between. It has been extensively harvested for the aquarium trade. On top of that, it is also highly susceptible to coral bleaching. Another contributing factor to its rapid decline is the destruction of its reef habitat. Due to these factors, IUCN has placed them on the red list as an endangered species.

Distinguishing Features
Distinct features include knoblike branches that appear to be irregularly dividing, which is a distinct feature of its colonies. Corallites can have a single spine, but they can also have no septa. Note that some specimens may have about one or two septa.

The corallites are usually small, only about 1 millimeter in diameter. Above the wall, you will also notice that the vertical spines tend to form into a palisade.

22. False Flower Coral (Anacropora spinosa)

The False flower coral is actually a type of briar coral. It is endemic to the Philippines and in the waters of other countries such as Japan. It can be found in much of the Pacific Ocean and the waters of the Solomon Islands.

Even though this species of coral is widespread across different territorial waters, the chances of finding it is slim. It is particularly susceptible to disease and coral bleaching. Combine that with the continued destruction of its natural habitat, and you have the perfect cocktail for killing coral populations. That is why Anacropora spinosa is included in the IUCN red list, which classifies this coral as an endangered species.

Distinguishing Features
False flower corals thrive in shallow reef areas. They appear pale brown in color when you observe them underwater. Its branches are usually around 10 mm in thickness, which tapers to a point and the end. You will also find that its spines usually project underneath. These corallites tend to elongate and have an irregular shape.

Sei Whale (Balaenoptera borealis)

Sei Whale (Balaenoptera borealis)

23. Sei Whale (Balaenoptera borealis)

Sei whales are the third largest whale species in the world. The only creatures larger than this animal are the Fin and Blue whales. They usually live in deep offshore waters, oceans, and other adjoining bodies of water.

The mature population of Sei whales has seen a huge decline, up to 80 percent, since the days of commercial whaling, which is why it is included on the IUCN's red list as an endangered species.

Distinguishing Features
Sei whales can reach up to 64 feet in length and weigh as much as 28 tons. Female Sei whales are a bit smaller, reaching up to 48 feet in length and weighing about 20.5 tons. Its diet usually consists of zooplankton, krill, and copepods. To keep up with its nutritional requirements, an adult Sei whale must consume up to 900 kg (around 2,000 lbs) of food daily.

The Sei whale is also one of the fastest sea creatures in the world. They can swim up to 31 miles per hour or around 27 knots, but they can only maintain that speed for short distances.

Blue Whale (Balaenoptera musculus)

Blue Whale (Balaenoptera musculus)

24. Blue Whale (Balaenoptera musculus)

Blue whales are the biggest animals on planet Earth. But size does not determine which species will dominate the animal kingdom. There are different types of blue whales, and most of the time, people refer to the North Atlantic Blue whale when referring to these creatures.

Other variants include the Southern Indian Ocean, Northern Indian Ocean, North Pacific, and North Atlantic Blue whales. Experts also note that due to the diversity and other uncertainties, there is no way to actually categorize Blue whales. That means trying to put them into categories is neither realistic nor appropriate.

The IUCN includes blue whales in the red list of endangered species due to an alarmingly reduced population. Experts estimate that the global population of blue whales has been depleted at a rate of 70 to 90 percent. This estimate includes all types of Blue whales.

The biggest threat to blue whales in the past was commercial whaling and exploitation, which was the major reason for their near extinction back in the 1960s. They were provided protection at the end of the 60s, but whaling operations continued. Whaling operations ceased in the 1970s.

There are still threats to the survival of this species–make no mistake. They are still prone to entanglements in fishing gear and ship strikes. The reduction of sea ice in the Antarctic will also affect migration, feeding, and breeding patterns.

Distinguishing Features
Blue whales are characterized by their slender and long bodies. They can weigh as much as 191 tons and stretch up to 98 feet long. Their colors usually consist of different shades of blue. Some are even bluish-grey. Their undersides tend to have a lighter color.

Fin Whale (Balaenoptera physalus)

Fin Whale (Balaenoptera physalus)

25. Fin Whale (Balaenoptera physalus)

Even though the cause of the major reduction in the global population of Fin whales is said to be reversible, it cannot be denied that they are also victims of the same sad history of commercial whaling. This is why IUCN still has this particular species on the red list as endangered.

Experts estimate that there is still a global decline in their population numbers among those in the southern hemisphere. The good news is that estimations indicate Fin whales in the northern hemisphere are increasing in population. The status of the subpopulation found in pacific waters is currently uncertain.

Distinguishing Features
Fin whales–like Sei whales–have long, slender bodies. They have a brownish-grey coloration on their upper sides and a paler shade on the undersides. They are larger than Sei whales but smaller than blue whales. The largest fin whale ever spotted was about 89.6 ft. The heaviest one ever recorded weighed 74 tons.

Russet Batomys or Dinagat Hairy-Tailed Rat (Batomys russatus)

Russet Batomys or Dinagat Hairy-Tailed Rat (Batomys russatus)

26. Russet Batomys or Dinagat Hairy-tailed Rat (Batomys russatus)

This rat species is classified as endangered on the IUCN endangered species list. It is estimated to have a small global population, struggling to survive on one island: Dinagat Island in the Philippines.

Experts point to the destruction of its natural habitat as the main reason for the population decline. Logging activities, mining, and agriculture are the main reasons for reducing nearby forest lands where the Dinagat hairy-tailed was known to thrive.

Distinguishing Features
This species is actually one of five under the Batomys genus. It was categorized as a separate species in 1998 and is known only because of two specimens collected back in 1975.

It is more or less an attractive mouse species. It has slick-looking fur that is rather thick. The fur on the upper part of its body is reddish-brown, while its underparts are orange-grey. The tail of this animal is short. It has long whiskers.

Limbless Worm Skink (Brachymeles vermis)

Limbless Worm Skink (Brachymeles vermis)

27. Limbless Worm Skink (Brachymeles vermis)

This unique reptile is endemic to the different islands of the Sulu Archipelago. They can be found in Tawi-tawi, Papahag, Bubuan, Butinian, and Jolo islands. This particular species is classified by the IUCN as endangered despite its wide range distribution, the rationale being the heavy deforestation in the aforementioned islands, two of which are completely deforested. The other islands have very small patches of forest remaining.

Lowland forest litter, detritus of the forest floor, loose soil, decaying logs, or any dry rotting material found on forest lands serve as the habitat of this species.

Distinguishing Features
Very little is known of the Limbless worm skink. They are only known to exist because of two specimens collected under leaves along a river bank. This is one of five known limbless reptile species in the world.

This particular species has six enlarged chin shields. It also has 22 to 24 rows of mid-body scales. It is also quite small, only reaching up to 74.7 mm. Its upper parts are dark-brownish, while its undersides are reddish and pale.

Loggerhead Turtle (Caretta caretta)

Loggerhead Turtle (Caretta caretta)

28. Loggerhead Turtle (Caretta caretta)

The Loggerhead turtle is included in the IUCN red list as a species vulnerable to extinction. The rationale behind its inclusion is based on the fact that ten subpopulations under this particular species are also vulnerable to extinction. The current population size of this species is currently unknown.

Researchers use the number of nests per annum to determine the population of these turtles. According to current trends, there are around 200,000 clutches laid each year. That is a combined total from all ten subpopulations. There is an estimated range of about 3 to 5.5 clutches for every female found of this species, equaling an estimated 36,000 to 67,000 nesting females annually.

The total nest counts of this turtle species still show a significant decrease, amounting to about 47 percent of the combined total numbers compared to previous estimates. This turtle species was categorized as an endangered species back in 1996.

The Loggerhead turtle has a global distribution. They mainly live in temperate and subtropical regions but can be spotted in different oceans and other bodies of water, such as the Atlantic, Indian, Pacific, and Mediterranean.

Distinguishing Features
This species is a type of marine turtle. On average, an adult turtle of this species will measure up to 35 inches in length. Adults can weigh up to 298 lbs. The largest specimen ever recorded weighed 1,000 lbs. This turtle's skin color ranges from yellow to brown hues. The shell, on the other hand, is usually reddish-brown. There are no gender-specific differences in size and features, except that males have shorter plastrons and thicker tails.

Dog-Faced Water Snake (Cerberus microlepis)

Dog-Faced Water Snake (Cerberus microlepis)

29. Dog-faced Water Snake (Cerberus microlepis)

This species of water snake is endemic to the Bicol Peninsula. Specimens have been found in Lake Manapao and Lake Buhi. This snake is also known locally as the Lake Buhi Bockadam.

The IUCN has included this species on its red list as an endangered snake species. This is because its habitat is considered very limited. For example, Lake Buhi only has 19 square kilometers (km). Its biggest threats today include the destruction of its natural forest habitat.

Pollution, including the increasingly poor quality of the lake water, contributes to the snake's population decline. Since this water snake can also thrive beyond its immediate lake habitat and surrounding areas, it may be growing and expanding its territory into other nearby forest areas. More studies and surveys are needed to ascertain its distribution and abundance.

Distinguishing Features
This water snake is characterized by the 29 scale rows found along its midbody. It also has one divided rear upper labial. One will also notice its keeled scales on its crown. On its rows of scales, the snake sports two lateral stripes. Its bodily scales form a uniformly dark ventral pattern.

Humphead Wrasse (Cheilinus undulates)

Humphead Wrasse (Cheilinus undulates)

30. Humphead Wrasse (Cheilinus undulates)

The Humphead wrasse is a species of fish that is included in the IUCN red list for endangered species. Due to several threats, the population of this fish is in decline. One of the culprits is unreported, unregulated, and even outright illegal fishing. Another issue is that there are local fishermen who do not know about the vulnerable state of the fish or that catching them is prohibited.

The lack of oversight from the local governments where these fish exist is also an important factor affecting their numbers. There is a lack of political will to enforce laws that would protect this species.

On top of that, the degradation and loss of its natural habitat greatly impact the population. To add insult to injury, some local fishermen still practice destructive fishing methods like using cyanide and dynamite. Needless to say, the illegal fish trade is a major problem in Southeast Asia.

Distinguishing Features
This species of fish is the biggest member of the Labridae family. Male Humphead wrasse can grow up to 2 meters long and weigh up to 180 kg. Females are a bit smaller than males.

Other distinct features include the two black lines behind their eyes, thick lips, and a hump that looks like its forehead. Its colors vary from blue-green to purplish-blue.

Green Turtle (Chelonia mydas)

Green Turtle (Chelonia mydas)

31. Green Turtle (Chelonia mydas)

Today's biggest threat to the Green turtle is illegal poaching, egg harvesting, and hunting. Many different human actions, intentional or unintentional, affect the lives of these marine turtles.

Unintentional encounters with this species include pollution, habitat destruction, entanglement in fishermen's nets, and boat strikes. Habitat loss occurs when former nesting grounds are turned into reclaimed, residential, or commercial areas.

Disease caused by pollution also kills a sizable portion of this species. The various diseases affect not only mature Green turtles but also hatchlings as well. These and other factors contributed to the rationale for putting this species on the list of species threatened by extinction, according to the IUCN.

Distinguishing Features
Male Green turtles have physical and developmental differences compared to females, making them distinguishable. Males usually have longer claws on their front flippers and a larger tail.

32. Black Shama (Copsychus cebuensis)

The IUCN includes this bird species on its red list and classifies it as endangered. It has a notably small population and a very small range. Both range and population have been observed to be on a decline.

Another threat to this species is the continual degradation of its natural forest habitat. That also contributes to its fragmentation, meaning the remaining forests cannot completely support the Black shama population.

It is estimated that around 1,000 to 5,000 Black shamas are living today. This is according to the latest survey taken in the Nug-as Forest. Experts estimate the population may even reach up to 6,500 Black shamas, but this estimate may be a generous one. However, experts estimate the population of mature Black shama to be somewhere between 670 to 3,300.

Distinguishing Features
This species has a black coat of feathers and can grow up to 20 cm in length. They also have a distinct bluish gloss at the tip of their wings. The recommendations may even have a bit of brown on them. The males tend to have brighter colored feathers than the females.

Panay Crateromys (Crateromys heaneyi)

Panay Crateromys (Crateromys heaneyi)

33. Panay Crateromys (Crateromys heaneyi)

This species is also known as the Panay cloudrunner. Just like other endangered species on the island of Panay, Crateromys heaneyi has also fallen victim to the massive deforestation on the island due to agricultural encroachment and illegal logging. It is believed that the creature mainly resides in the remaining forest area on the island's western side, at an elevation of 400 m. Residents also claim that the rodent can also be found at higher altitudes.

More surveys need to be conducted to ascertain the population size, but experts presume the degradation of the forest has caused the population to decline.

Distinguishing Features
This rodent species is the second largest cloud rats family in the country.

An adult Panay cloudrunner can grow up to 600 mm in length. It has a long bushy tail, and the rest of its body is covered in greyish brown colored fur. This species is nocturnal and can be found nesting in the hollows of trees. The usual diet of these animals includes an assortment of leaves, papayas, corn, guavas, bananas, and other fruits.
