XXX. Mammals
All mammals have fur or hair and feed their babies. Giraffes, bears, kangaroos, elephants and people are all
mammals. They produce milk.
It's usually the female mammals who choose a mate, so the males want the females to look at them.
Leopards make marks on trees with their claws so that the females will know they are there. Other animals
make special smells. Males often fight with each other to win a mate.
Most mammals do not lay eggs. The babies grow inside the mother's body, and they get food and oxygen
from a special part of the body called the placenta. This is called gestation. The gestation time for shrews is
only two weeks but for African elephants it's 22 months.
When mammals are ready to have their babies, many look for safe, quiet places. Polar bears dig special
dens in the snow so that their babies will be warm and safe.
Baby mammals
Some baby mammals grow a lot inside their mother's body and they can stand up as soon as they are born.
Other baby mammals can't see or move when they are born. Mammals produce milk for their babies, and
this is the only food or drink that they need at first.
Mammals are different from many other types of animal because they feed and care for their babies.
Anteaters carry their babies on their back for the first year, and elephants stay near their mother until they
are ten years old. Baby mammals learn from their parents and they learn by playing, too.
Life is very dangerous for a lot of animals. Many are killed by predators. Also, people hunt them and
damage their habitats - the places where they live.
Many animals die before they become adults, but if they grow up, then they can produce young. This is all
part of their life cycle. Because of this, there will always be millions of species of animal on Earth, if we
care for them and their habitats.
