The scientific name for the koala is Phasclarctos cinereus. Koalas are warm-blooded mammals that live on the East Coast of Austrailia. They live and sleep in eucalyptus trees. They sleep up to 19 hours a day and can live to be more than 20 years old.
Koalas eat the leaves from the eucalyptus trees.
They eat about 2.5 pounds of food each day. Koalas weigh between 15 and 30 pounds. Koalas have both sharp teeth and claws. Their fur is white on the underside and grey everywhere else. Koalas breed in the summer and they produce about one young per year.
