When you’re thinking how many animals exist in this world, it’s simply overwhelming. The beauty of nature couldn’t be complete without them. We can learn so many things from them such as loyalty, courage and love. The truth is that every single animal has an unique thing that makes him special.

Check out these awesome facts you didn’t know about animals! 

Housefly

Houseflies don’t allow their short lifespans (14 days) to hinder their musical abilities. They always hum in the key of F.

Ostrich

Ostriches can run faster than horses, and the male ostriches can roar like lions.

Bat

Bats are the only mammals that can fly, but wouldn’t it be awesome if humans could fly too?

Kangaroo

Kangaroos use their tails for balance, so if you lift a kangaroo’s tail off the ground, it can’t hop.

Spider

On average, there are 50,000 spiders per acre in green areas. Bet you’ll think twice before going outside now – unless you’re this guy.

Tiger

Tigers not only have stripes on their fur, they also have them on their skin. No two tigers ever have the same stripes.

Crocodile

Here’s a tidbit that might be useful if you plan on becoming the next Steve Irwin: To escape the grip of a crocodile’s jaw, push your thumb into its eyeball – It will let you go instantly.

Cat

A cat has 32 muscles in each ear. All the better for them to eavesdrop on your conversations and plot your demise.

Elephant

Elephants can smell water up to 3 miles away. They are also one of the three mammals that undergo menopause – the other two being humpback whales and human females.

Koala

Koala bears almost exclusively eat only eucalyptus leaves and nothing else.

Beaver

Because beavers’ teeth never stop growing, they must constantly gnaw on objects to keep them at a manageable length. Their teeth would eventually grow into their brain if they didn’t maintain them.

Ant

Beware an ant uprising! There are one million ants for every human in the world. These resilient creatures also never sleep and do not have lungs.

Oyster

Oysters can change gender depending on which is best for mating. Talk about successful adaptation.

Butterfly

Butterflies have two compound eyes consisting of thousands of lenses, yet they can only see the colors red, green and yellow.

Snail

Don’t try this at home, but a snail can grow back a new eye if it loses one.

Turtle

You can tell a turtle’s gender by the noise it makes. Males grunt and females hiss.

Giraffe

Giraffes have no vocal cords and their tongues are blue-black in color.

Squirrel

You might want to thank a squirrel the next time you enjoy the shade of a tree. Millions of trees are accidentally planted by squirrels that bury nuts and then forget where they hid them.

Blue Whale

Humpback whales create the loudest sound of any mammal. And you thought the loudest sound came from that two-year-old you sat next to on your trans-continental flight, didn’t you?

Dog

Dogs’ nose prints are as unique as human fingerprints and can be used to identify them.
