Where do Mammals live?

Mammals are found in every kind of major habitat all over the world!

Most live on land - this can be living underground, on the ground, in the trees, in the mountains, in the dessert, in the coldest places and the warmest.

There are some mammals that live both in the land and the water, like beavers, seals, otters. Some live only in the water, like whales, dolphins, narwhals and manatees.
Marine mammals like whales, narwhals and dolphins have to come up to the surface to breathe through blowholes on their backs.

They can be very tiny, like little mice, or huge like elephants, giraffes and whales.

There are some special mammals that have pouches for their babies to grow in, called marsupials, such as kangaroos, koalas and possums. These mammal babies stay in the mother's pouch until they are fully developed.

Bats are another kind of special mammal because they have 2 wings and can fly, and 2 feet.
