Lions are meat-eating mammals that like to live in groups or families. A lion's family is called a “pride.” Usually there will be many females that live together along with their cubs, but only one male. Lions like to play and hunt together. Because they have a keen sense of hearing and sight, they often will hunt at night. Usually the females do the hunting. They work in groups to catch their prey. The male lion takes his share of the catch before the females and cubs get any food. Lions are known for their loud, ferocious roar.

Have you ever seen a cuddly looking koala? Most people call them koala bears. But koalas aren't bears! In fact, koalas aren't even related to bears. Koalas are mammals called marsupials. Marsupial means “pouched animal.” Koalas carry their babies in pouches just like kangaroos. Koalas are picky eaters. The only food that a koala will eat is eucalyptus leaves. Eucalyptus leaves are found in Australia, so koalas live in Australia. Koalas are “nocturnal” animals, which means that they sleep during the day and are awake at night.
