Koala
The Koala or, inaccurately, koala bear (Phascolarctos cinereus) is an arboreal herbivorous marsupial native to Australia. It is the only surviving member of the Phascolarctidae family, and wombats are its closest living relatives. The koala inhabits Queensland, New South Wales, Victoria, and South Australia in the eastern and southern coastal parts of the Australian mainland. Its robust, tailless body and huge head, which has round, fluffy ears and a large, spoon-shaped nose, make it easy to identify. The koala weighs 4–15 kg (9–33 lb) and has a body length of 60–85 cm (24–33 in). Silver grey to chocolate brown is the different shades of fur. Generally speaking, koalas from the northern populations are smaller and lighter in color than their southern counterparts.
Due to the fact that they eat mostly Eucalyptus leaves, koalas prefer to live in open Eucalyptus woodland. Koalas spend much of their time inactive and sleep up to twenty hours a day due to the low nutritional and calorie content of their eucalyptus diet. They are asocial creatures that only form bonds with their dependent offspring's mothers. Male adults use loud bellows to communicate with one another deter rivals and entice partners. Scent glands on the males' chests produce secretions that they use to signal their presence.
