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.

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.

Flea

Fleas can jump up to 200 times their height. This is equivalent to a man jumping the Empire State Building in New York.

Cat

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

Koala

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

Oyster

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

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.
