Cool Animals List With Pictures & Facts: The World’s Coolest Animals

A list of cool animals, with pictures and interesting facts. What are the world’s coolest species? Read on to find out…

What Are The Coolest Animals?

A cool animal might have special abilities (aye-aye, cheetah, immortal jellyfish); it might look cool (maned wolf, narwhal, proboscis monkey); it might be particularly badass (electric eel, honey badger, polar bear); or it might have an amazing lifestyle (arctic tern, wandering albatross, emperor penguin).

In compiling this list, we’ve only included living animals; would the Komodo dragon really have made the grade if Tyrannosaurus rex had been in the running? Snow leopards are cool and all, but are they as cool as American cave lions? (Actually, yes, not many animals are as cool as snow leopards!)

If you want to see cool prehistoric animals, then check out these pages:

Sadly, many of the cool animals on this list are endangered. We’ve included the IUCN Red List conservation status (checked 09/22/23) of each species on the list.

This is our list of cool animals… what species are in yours? Let us know the animals you agree with (and any cool animals we’ve missed out) in the comments section at the bottom of the page!

The Rhesus Macaque is one of the best-known species of Old World monkeys and is known for its wide range of vocalizations. It has a highly diverse diet and is adaptable to multiple habitats but prefers mixed wooded areas close to water. It is of significant importance in medical and biological research due to its closeness to humans, anatomically and genetically.
