We cannot see the ears of some animals. These
animals have internal ears. Birds have tiny holes
on both sides of their head. These are covered
with feathers. Snakes and lizards do not have
ears. They feel vibrations on the ground to know
about the presence of other animals.
* Although hippopotamus is a big animal, it has small ears.
* It seems that the snake is dancing to the tune of the snake charmer. Actually, it
just follows the movement of snake charmer’s bean!
Hair and Fur
Some animals have hair on their body. Some animals have long hair on their
skin and some animals have small. Animals like yaks, musk oxen and bears
that live in very cold areas have long hair which keep them warm. Animals
like cows and buffaloes have short hair.

You will observe that the animals which have external ears also have body
hair. Such animals are called mammals.
Animals like porcupine and hedgehog have needle like hair on their body. It
helps them to protect themselves from their enemies.
The different designs on an animal’s skin are due to the presence of different
coloured hair.
A leopard has spots on its body. Tigers have striped coat.
