What are structural characteristics of koalas?

Answer 1

Koalas are four-legged warm-blooded vertebrates. They are mammals; specifically, they are marsupials. As with all marsupials, the koala has a pouch, where the joey stays after birth for up to ten months. When the joey leaves the pouch, it stays for several more months on the back of their mother. The pouch opens backwards.

Koalas have very strong claws suitable for gripping trees and climbing. Between their first and second "fingers" is a large gap, which enables them to also grip tree branches comfortably, whilst their hind legs have one toe set at a wide angle. They also have toes with thick pads which enable them to sit comfortably in a tree all day.

In order to attract a mate, the male has a scent gland which emits a very strong scent.

Koalas in southern regions have thick, wool-like waterproof fur to keep them warm in cold weather and dry in rain. Koalas in northern regions are smaller, with less dense fur.

Answer 2

Koalas have a compact body with a large head and round ears. They have sharp claws for climbing trees and gripping branches, as well as a thick, woolly fur that helps protect them from the elements. Koalas also have a unique digestive system adapted to their diet of eucalyptus leaves.
