What are tails for?

Tails

The tails of animals are good for many things.  Jumping animals, such as cats and kangaroos, use their tails for balance.  Many monkeys use their long tails to help them climb trees.  

Horses and cows swish away pesky insects with their tails. A fish swims with its tail, of course, and so do many other water creatures.  A bird without a tail would have a hard time taking of and landing. 

Dogs give special messages to other dogs by wagging their tails.  One kind of wag means, “I’m happy to see you.”  Another means, “I’m the boss around here.”–Dick Rogers
