Mammals are the highest class of vertebrates and the female has mammary glands which secrete milk for the nourishment of young after birth. Mammals are warm-blooded and the majority of their body is covered with hair. Mammals give birth to live young (except the platypus and echidna, who lay eggs). They also have three middle ear bones.
Most mammals live solely on land, but there are several groups that have specifically evolved to exist solely in aquatic environments (dolphins and whales) one of which is the largest of all animals. Only one group has mastered the art of true flight (bats) although several have developed the ability to glide through tree tops.

ANIMAL FACTS - Camels
Camels can go weeks between drinking, and are able to drink brackish and salty water. Most moisture is obtained from the food they eat. If there is not a lot of food around, the camel will utilise the fat stored in the hump on its back. The hump shrinks and fattens depending on lack or excess of food. Camels have a complex digestive system that allows them to eat many toxic plants. They eat around 80% of the plant life in the dessert, from spiky cactus, to saltbush.
