Koala

Females reach maturity at 2 to 3 years of age, males

at 3 to 4 years. A healthy female koala can produce

one young each year for about 12 years. Koalas

spend about three of their five hours

eating. They feed at any time of day, but usually at night.

It is generally a silent animal, but males have a very

loud advertising call that can be heard from almost a

kilometre away. The koala will eat the leaves of a wide

range of eucalypts, and occasionally even some non-eucalypt

leaves.
