The Smallest Animals in the World

Angela, an animal lover, has a passion for learning and understanding God's creatures. As a born teacher, she enjoys sharing her knowledge.

There is something neat about the largest and the smallest of God's creatures. Even Hollywood's elite enjoys carrying around the tiny Chihuahuas as a symbol of their status. Whether it's because they look like a baby version of their larger ancestor or because they are so odd, small creatures often attract attention from people.


The Smallest Monkey - Pygmy Marmoset

The Pygmy Marmoset is the smallest monkey and one of today's smallest primates. It measures between 14 and 16 centimeters long and weighs 4 to 5 ounces, excluding its tail. The males weigh at the higher range of this, whereas females weigh at the lower end of this range. They live up to 11 years old and usually eat small insects, leaves, and fruit, but their favorite is sap from trees. It will spend long periods trying to tap the sap out of a tree.

They communicate with one another through a few means. The more apparent means is by using different high-pitched tones that range from chirping to shrill whistling and even screeching. They also communicate with one another through their scent.

Another unusual habit they have is defecating and urinating on their paws to have a better grip when they climb.

Smallest Dog Breed - Chihuahua

The Chihuahua is the smallest dog breed. They are named after the state of Chihuahua in Mexico since that is where the first Chihuahua lived. They are very nervous animals that tend to be fiercely loyal to one specific owner. They also tend to like other Chihuahuas and can be aggressive to other breeds.

The height of a Chihuahua varies proportionately more than any other breed out there. The standard weight range is from 3 to 7 pounds, but smaller Chihuahua's exist. The British believe this kind of breed's preferred weight is between two and four pounds. Some Chihuahuas weigh as much as 10 pounds or more, but they are generally considered overweight for their breed.

An Adorable Small Antelope - Damara Dik Dik

The Damara dik-dik is a small antelope animal named after the "dik-dik" or "zik zik" noise they make. They are about 12-16 inches tall and 20-28 inches long. They usually live in East Africa, Nambia, and Angola, although hunters feel they are a nuisance because they often scare away larger game animals. Many have been killed just because of the distraction that they cause.

The females are generally larger than the males, and the males also have horns that point backward. This one to the right appears to be a female. They are herbivores and primarily eat fruits, shoots, foliage, and berries. They have four stomachs, and much like cows, they will chew the cud; in other words, they will regurgitate the food swallow it again.


One of the Tiniest Frogs in the World - Gardiner's Frog

These frogs never grow bigger than the size of a dime at 11 mm. When they first hatch, they are only 3 mm in length, a third the size of a dime. Most adult males are only 8 mm long. The frog is beaten out as the smallest by Brazilian Gold Frog and Monte Iberia Eleuth. They generally eat small insects like mites or ants.

Smallest Mammal - Kitti's Hog-nosed Bat

The Kitti's Hog-nosed Bat, also known as the bumblebee bat, is not only the smallest bat ever but even the smallest mammal in the entire animal kingdom. They live in Thailand. It weighs less than a penny when it is full-grown and is less than 33-40 mm in length. They make homes in hot limestone caves in Thailand because staying warm is not an easy task due to their tiny state.

They feed on insects and tree leaves, such as bamboo and teak trees. They are currently one of the most endangered species in the world due to the destruction of their habitats. They are named hog-nosed bats for apparent reasons. Their nose is pig-like. They also have very pronounced swollen ears and have no tail.

Smallest Known Dinosaur - Compsognathus

According to an article printed in 2001, the Compsognathus was the smallest dinosaur. The same article stated that scientists believed there was an even smaller dinosaur before this finding, but after further research discovered that the bones were actually from a baby of a much larger dinosaur. So these findings are subject to change if they have not already. Although since dinosaurs are extinct, we may find fossils to an even more diminutive dinosaur.

It is about 6.5 pounds and slightly larger than a chicken. Some believe it looked almost bird-like, while others believe it is more lizard-like.

Sun Bear's though not diminuitive, are the smallest of all bears.

Smallest Bear - Sun Bear

The Sun Bear or a honey bear is the smallest in the bear family at 4 feet or 1.2 meters tall. Males tend to be larger than their female counterparts. Unlike many of its family members, the sun bear does not hibernate and lives in the rainforests in Southeast Asia. Contrary to its name, the sun bear is nocturnal and spends most of its time within the woods.

Their love of hiding in the trees destroys personal property, which causes some men to hunt these animals due to feelings of them being a nuisance. They are not yet considered endangered, but their population is on a decline. Unlike any other bear, its temperament and size make it somewhat desirable as a pet.

Thumbelina the smallest horse.

Current Smallest Horse (2010) - Thumbelina

As of 2010, the current record holder for the most petite horse that ever lived is Thumbelina, a miniature horse affected by Dwarfism. She stands 17 inches or 43 centimeters tall as a fully mature horse. She weighs 60 pounds or 27 kg.

The oldest horse also had Dwarfism. It was a horse named Angel that lived over 50 years old. Also, some people have trained horses that were affected by Dwarfism as leaders for the blind. There is a controversy about whether this is the right decision or not.

Fennec actually means fox, so the fennec fox literally means the fox fox.

Smallest Fox - Fennec Fox

The fennec fox has earned the status of being the smallest fox with 1.5-3.5 pounds. It is between 9-16 inches tall or 24-40 cm. Proportionately, their ears are significant for their little body, measuring at 3.9-5.9 inches or 10–15 cm. Unlike most foxes, they have adapted to desert-like conditions. Even its coat, ears, and kidney have adapted. Their adorable large ears are so sensitive that they can hear their prey underground. They mainly eat rodents, birds, insects, and eggs. The name fennec fox comes from the Arabic word fennek, which means fox, so their name is essentially fox fox.

Thank you so much for the great compliment! I too think they are so adorable!!!

Peg Cole from North Dallas, Texas on September 01, 2010:

The Marmoset are my favorite - so adorable. Hard to believe they are that tiny. Really enjoyed reading this well written and informative hub. Thank you.

Angela Michelle Schultz (author) from United States on May 26, 2010:

Thanks so much for the great compliment. Well, I know of course the Chihuahua can be a pet, but the Pygmy Marmoset although can actually be a pet, but you need to do a lot of research before you get one, since they often die due to inexperienced marmoset owners.

kuboje on May 26, 2010:

All these smallest animals are so cute, wonder if we can keep them in our house as pet? Great job, thanks for sharing, been looking at those pictures over and over again...and still amaze me like the first time I saw them.

Angela Michelle Schultz (author) from United States on May 22, 2010:

Yeah, I can see that. I love Anne Geddes! My roommate in college covered her room with posters of Anne Geddes!

stevewong on May 22, 2010:

That Chihuaua is adorable. The picture reminds me of the Anne Geddes stuff!

Angela Michelle Schultz (author) from United States on May 21, 2010:

Thanks Money Glitch. I think my personal favorite from the list are the pygmy marmosets. They are so cute and small, although I heard that most people who choose to have them as pets, do not take care of them properly due to lack of knowledge.

Money Glitch from Texas on May 21, 2010:

Great hub, thanks for sharing the worlds smallest animals, some of these 'god's little creatures" I'd never seen or heard of. Great Job! :)

Angela Michelle Schultz (author) from United States on May 20, 2010:

Springboard, interesting. There is a couple other ones that are close to beating Thumbelina, but she was the smallest according to several sites and wikipedia. Unless I find out otherwise, she's staying on the list.

Angela Michelle Schultz (author) from United States on May 20, 2010:

Thank you so much GeneralHowitzer. I'm glad you enjoyed it. I find all these animals absolutely fascinating! They are by far my favorite topic to write on!

Springboard from Wisconsin on May 19, 2010:

Great hub. Very cute little critters. :) Incidentally, saw a clip on Talk Soup about a miniature horse. No bigger than a mid-sized dog. Very cute indeed.

Gener Geminiano from Land of Salt, Philippines on May 19, 2010:

Wow one of the best hub about these wonderful creatures. The Sun Bear is threatened in China they were caged and farmed of their bile, if my memory serves me right thanks for sharing... Rated Up great job here eh... Gotta back for more in the days to come to read some of your wonderful stuffs... By the way I have some tips for you in your email...

Angela Michelle Schultz (author) from United States on May 18, 2010:

Oh, I bet I will, I better go check it out! Maybe it's an animal that needs to be added briefly to this hub. LOL... if so I'll make a link to your hub as a result!

Garnetbird on May 18, 2010:

Adorable Hub--especially loved the little antelope. You might like my Hub on the little Dartmoor Pony.

Angela Michelle Schultz (author) from United States on May 18, 2010:

Yes, He is, the amazing thing is there are animals out there, we have never heard of. In fact, recently there was a bird they thought was extinct, that was discovered deep in the rain forest. It was so fascinating!

menomania from Elmira, New York on May 18, 2010:

Thank you for a very interesting hub. Our God certainly was creative when He created the animals of this world.

Angela Michelle Schultz (author) from United States on May 16, 2010:

Although Sugar Gliders are extremely cute, and small. The smallest marsupial goes to (drum roll please) the long-tailed planigale at 55 mm. Due to lack of pictures that are royalty free I did not post it. But it's definitely interesting looking. It could sleep on your thumb. I think it's probably good my husband has not heard about sugar gliders as pets, I think I'd have trouble convincing him, we shouldn't get one.

stevewong on May 16, 2010:

My friend had a sugar glider before. I believe it is the smallest marsupial : ) She actually let him sleep in her shirt during the day (it's nocturnal).

Angela Michelle Schultz (author) from United States on May 16, 2010:

Yes, I absolutely love animal articles... obviously! The photos were really hard to find. I got them all from gettyimages. The same with the biggest animals. There were some I wanted to write about, but couldn't get a royalty free pic. :)

Angela Michelle Schultz (author) from United States on May 16, 2010:

Ultimate Hubber, actually I got the inspiration for this hub, because of a book one of the kids I nanny for came home with. It was the biggest and the smallest animals. I started with that and broke it down to many hubs, but more in depth information. The book also had slowest, fastest, and all the -ests there are.

BkCreative from Brooklyn, New York City on May 16, 2010:

So interesting. I love articles this, anything about the other animals we share the earth with - and thanks for the photos.

Ultimate Hubber on May 16, 2010:


I have been reading about animals lately and loved this hub. Where did the inspiration for this hub come from?

Angela Michelle Schultz (author) from United States on May 16, 2010:

Thank you very much. Actually I copied and pasted it from my other hubs, I must have forgotten to edit it, thanks for letting me know. :)

Rema T V from Chennai, India on May 15, 2010:
