Watch in a different language
Mammals are viviparous meaning that they are born from their mother’s womb. In their early stages of live they feed on milk which they get from their mother’s breast. Mammals reproduce by internal fertilization when a sperm cell and an egg join inside the female. They have teeth inside their mouths and lips around them so that they can eat and suck milk. Most mammal’s bodies are covered in fur and all mammals breathe with their lungs even though they live in the sea like the dolphins and whales.
Mammals have four limbs which vary depending on where they live. Land mammals have legs, aquatic mammals or marine mammals have fins and mammals which can fly such as bats have wings.
Depending on what they eat they can be herbivores (cows), carnivores (lions) or omnivores (human beings).
