Mammals

A vixen is a female fox.

A wallaby is a name given to any small kangaroo. Both wallabies and kangaroos are from Australia. They can survive in very dry climates, and hop along on their back legs using their tail as a balance.

The warthog is a king of pig that lives in Africa. It has a lumpy face, hence the name warthog. Warthogs have two pairs of tusks which they use to fight and dig for food.

Whales are a large animal that lives in the sea. They are not fish, as they need to come to the surface to breathe, the same as we do when we are swimming. There are many different varieties of whale. Some eat fish, penguins and seals, but the majority of whales have a large mouth full of tiny bristles that they use to filter tiny sea animals out from the water to eat.
The whale is closely related to the dolphin.

The wolf is the wild relative of the dog. They live in forests and sometimes grasslands. Wolves generally hunt deer or any other available animal. A baby wolf is called a puppy.

Wombats are a marsupial that lives in Australia. Marsupials are animals that keep their babies in pouches. The wombat's pouch faces backwards so it doesn't fill up with dirt while the mother wombat is digging. Wombats dig large systems of burrows, both to live in and while looking for roots to eat. The closest relative of the wombat is the koala.

Zebras are a relative of the horse, and they live in Africa. They travel around in large groups called herds. All zebras are black and white striped.
