Mammals are animlas with mammary glands. The females produce milk in their mammary glands to feed their young.
  • The majority of mammals are terrestial and have four legs for walking with. Some mammals, like seals and whales live in the sea and have fins instead of legs. Other mammals, like bats, can fly because they have wings.
  • Most mammals are covered with hair or fur. Some have little or no hair, like elephants and whales.
  • Mammals are warm-blooded animals: they keep their body temperature at a constant level. When it is cold, their fur and the layer of insulating fat beneath their skin help animals to retain body heat. When they are too hot, they lose heat through their skin by sweating.
  • All mammals have lungs for breathing with.
  • Mammals are viviparous: they give birth to live young. The parents take care of the young until they ready to live on their own.
