A Bit of Background on Endangered Species and Animals

In a survey (note: this link goes to an independent website's archived copy; the museum's original link no longer exists) of biologists conducted by New York's American Museum of Natural History, 70% of the biologists surveyed believe that 20% of all living animal populations could become extinct by 2028. Science has only identified about 2 million species, but it is estimated that this is only a small fraction of the number that have yet to be discovered or have already gone extinct. Over the past 400 years, 89 mammalian species have gone extinct, and another 169 are threatened with extinction.

Because of human destruction of their habitats, tropical rainforest species are at the highest risk, as are top-of-the-food-chain carnivores, other species whose geographical range is already small, and marine coral reef species.

While the fossil record shows that the loss of biodiversity due to extinctions is a phenomenon that can be recovered from, the time for recovery in the past has been on the order of millions of years. If we humans don't take action to maintain our planet's biodiversity, we might face extinction in the future.

Here are 10 of the world's most endangered species. There are many more species that are endangered or threatened with becoming endangered, but most of these are considered to be at extreme risk of extinction.

  1. Siberian Tiger
  2. Bonobo Ape
  3. Giant Panda
  4. Mountain Gorilla
  5. Black Rhino
  6. Hawksbill Turtle
  7. Sumatran Orangutan
  8. Fin Whale
  9. Asian Elephant
  10. Amur Leopard
The Siberian Tiger

The Siberian Tiger

1. Siberian Tiger

  • Scientific name: Panthera tigris altaica
  • Location: Russian Far East, possibly small border areas of China and North Korea.
  • Population: 450

Tigers once ranged all over Asia, but today their numbers are dangerously low, and more tigers exist in American zoos than in the wild in Asia. The Siberian, or Amur, tiger is the sub-species closest to extinction in the wild. These are the largest-sized sub-species of tiger and the largest of the world's big cats.

These big cats' major threats are poaching and habitat loss due to human encroachment. Much of the poaching is done to supply tiger parts for traditional Chinese medicine, even though equivalent modern alternatives are available and have been proven to be more effective.

The Bonobo Ape

The Bonobo Ape

2. Bonobo Ape

  • Scientific name: Pan paniscus
  • Location: Central Africa
  • Population: 5,000 to 60,000

Bonobos are members of the great ape family and are found only in the rainforests of the Democratic Republic of Congo. They are closely related to the more familiar chimpanzee, with longer legs, shorter arms, and smaller trunks. Like chimpanzees, bonobos are remarkably social, but bonobos tend to be more peaceful than chimps.

Aside from the limited range of their habitat, the greatest threat facing bonobos is poachers who kill the apes and sell them for bush meat.

The Giant Panda

The Giant Panda

3. Giant Panda

  • Scientific name: Ailuropoda melanoleuca
  • Location: South-central China
  • Population: 1,864 as of 2014

One of the most familiar endangered species in the world, the giant panda spends half its day eating, and bamboo makes up 99% of its diet. While poaching is no longer considered a threat, the main threat to the giant panda is the loss of habitat and fragmentation of their habitat due to agriculture.

4. Mountain Gorilla

  • Scientific name: Gorilla beringei beringei
  • Location: Central Africa
  • Population: 700

The sub-species of gorilla known as the mountain gorilla exists in the wild in two small regions: the Virunga Volcanoes region at the borders of Uganda, Rwanda, and the Democratic Republic of Congo, and the Bwindi Impenetrable National Park in Uganda.

These animals are threatened by hunting and human encroachment on agriculture and timber. While eco-tourism may help to protect these small populations, there is a risk of spreading human illnesses to the animals.

The Mountain Gorilla

The Mountain Gorilla

The Black Rhino

The Black Rhino

5. Black Rhino

  • Scientific name: Diceros bicornis
  • Location: Southwest Africa
  • Population: 4,000

The black rhino was once the most numerous rhino species in southwestern Africa. Due to excessive hunting, the population has been reduced by over 90% in just the last 70 years.

The greatest threat to the black rhino is poaching. They are hunted simply for their horns, used in traditional Chinese medicine, and for trophies and ornamental use.

Increased law enforcement and conservation programs are helping increase their numbers, but they are still considered critically endangered.

The Hawksbill Turtle

The Hawksbill Turtle

6. Hawksbill Turtle

  • Scientific name: Eretmochelys imbricata
  • Location: Throughout the tropics and subtropics
  • Population: 8,000 nesting females

With a range that covers all the world's tropical and sub-tropical seas, the hawksbill turtle population has decreased by 80% over the last three generations.

The major threat facing the hawksbill turtle is the tortoiseshell trade. In the last 100 years, millions have been killed for their shells. Habitat destruction by human beach front development, excessive collection of their eggs, and poaching for meat are other major threats to their survival.

The Sumatran Orangutan

The Sumatran Orangutan

7. Sumatran Orangutan

  • Scientific name: Pongo abelii
  • Location: Northern Sumatra
  • Population: 7,300

Sumatran orangutans exist only on the Indonesian island of Sumatra. Over the last 75 years, their population has been diminished by 80% due to human encroachment of their forest habitat, especially for timber and agriculture.

Although their numbers were stabilizing for several years, logging increased as people cut down trees to rebuild damaged infrastructure following the 2004 tsunami.

The Fin Whale

The Fin Whale

8. Fin Whale

  • Scientific name: Balaenoptera physalus
  • Location: All the world's oceans
  • Population: 30,000

In the 20th century, over 750,000 fin whales were killed by commercial whalers. This second largest living animal (after the blue whale) was hunted almost to extinction until the International Whaling Commission's ban on killing them in 1976. Except for a small number of allowed kills for Norway, Japan, and Iceland, the hunting of this whale has been banned.

The Asian Elephant

The Asian Elephant

2. Asian Elephant

  • Scientific name: Elephas maximus
  • Location: India and Southeast Asia
  • Population: 25,000 to 32,000

The main threat to Asian elephants is conflict with humans. Since elephants are grazing animals, they need large tracts of land to feed and survive. Because of this, elephants and people cannot co-exist in regions where most of the land is used for agriculture.

The habitat of the Asian elephant lies within Asia, the area of the world with the greatest human population growth, so their habitat is under serious threat from human encroachment.

The Amur Leopard

The Amur Leopard

10. Amur Leopard

  • Scientific name: Panthera pardus orientalis
  • Location: Eastern Russia
  • Population: Less than 40

Once ranging from all over Eastern Asia, the Amur leopard, or Far Eastern Leopard, is now extinct in China and the Korean Peninsula.

Poaching and human encroachment into the habitat of the Amur leopard have led to their drastic reduction in numbers. With such a small population, genetic anomalies due to inbreeding pose a further threat to the population.

Great article. Inspiring. This will help raise levels of awareness.

nickupton from Bangkok on August 08, 2011:

Nice hub that gets people thinking about humankind's effect on wild animals. Anything that makes people think about that is great work. Whilst the world's most endangered species are difficult to keep track of I can think of many that are far more endangered than some of these; Spoon-billed Sandpiper (down to 150-300 birds and declining rapidly), Javan Rhino (only 50 left), Sumatran Rhino (less than 500?).

IndoVillas on May 25, 2011:

People should be more aware of this things and consider the importance of survival of the species. Great hub!

Animal gal on February 11, 2011:

Personally I am an animal fan. It was so painful reading about these endangered species. There definatly has to be something done. The one that caught my eyee was the Amur Leopard. In hope there is a solution!

slow loris on February 05, 2011:

The trade in animal body parts for traditional medicine is a massive cycle that we have to break. Often, it's just the unavailability of modern medicines and belief systems of those living in remote areas of the world, that keep this practice going. It's something that could be easily fixed and would save the lives of so many animals.

gr8 website !!!!

Spm777 on January 22, 2011:

I need people to know about these animals i think if they die all go with them!!!!

Miss Lil' Atlanta from Atlanta, GA on January 12, 2011:

It's such a shame to know that these beautiful animals are on the endangered species list. By killing off this unique wildlife, we're ridding of some of the animal kingdom's best attributes.

glenn wallace on January 07, 2011:

Great hub!

I've had the honor of seeing a black rhino, and baby, in the wild. They were standing on a ridge maybe 200 yards away in a game preserve in Tanzania. It was humbling to see, even at that distance. I'm saddened thinking that such an amazing and beautiful animal might not be around for my children to see.

person on December 14, 2010:

i think we should save all of the indgered animals

Thanks for letting the world know that animal too need a space to live ...!

yash shah on June 26, 2010:

hey i am very sad to see that many species are endangered pls save these species we need them

emily on June 19, 2010:

i like the photos and that how you got up all those great creatures you should make another web site with animal info i loved to see that lol

mickey on June 10, 2010:

we should save all d animals

cutie on June 02, 2010:

this list is very nice and we the coming generation should contribute to save these precious species so we should try to save these animals

FlyingSquirrel from Western US on May 12, 2010:

Sorry, but there are many species in much greater extinction danger than the list here.

Try the Vaquita. Ot the now extinct Baiji, the first specimen of mega-fauna to go extinct in our lifetime.

This list is nice, but far from the Ten most "endangered" species.

Edweirdo (author) from United States on May 12, 2010:

Excellent point, BritFun, and well put.

Thanks for contributing...

BritFun from Oxford on May 12, 2010:

Fascinating hub.

What we're doing to these species is unforgivable - and you can bet future generations won't forgive us.

There's something very wrong with a world that has more than 6 billion people (that's 6,000,000,000) and only 40 Amur Leopards. The two facts are not un-related. A few less of us might leave more room for a few more of them.

Chapter from Indonesia on May 11, 2010:

good hubs. I know the endangered species. Orangutan is also found in Borneo besides Northern Sumatra. It is very clever. My mother had a pair of orangutan. He can imitate human sound. Off course, it cannot talk.
