Koala
Scientific Name: Phascolarctos cinereus
Category: mammal
Brief Description
An arboreal herbivorous marsupial native to Australia, recognized by its stout, tailless body and large head with round, fluffy ears.
Characteristics
Stout, tailless body, large head with round, fluffy ears and large, spoon-shaped nose. Thick, ash-grey to yellowish-brown fur. Sharp claws for climbing. Males are generally larger than females and have a scent gland on their chest.
Habitat
Eucalyptus forests and woodlands in eastern and southern Australia.
When to Find It
Can be observed year-round, mostly active at night (nocturnal) but often seen resting in trees during the day.
Conservation Status
Vulnerable (IUCN Red List), endangered in some Australian states due to habitat loss, disease (Chlamydia), and climate change (bushfires).
Ecological Role
A key herbivore in Australian forest ecosystems, relying almost exclusively on eucalyptus leaves. They contribute to the pruning of trees and nutrient cycling.
Easily Confused With
There are no highly similar animals in Australia, though from a distance, other arboreal marsupials like possums might be confused, but koalas are much larger, lack a tail, and have a distinct body shape.
Observation Tips
Look high in the forks of eucalyptus trees where they often rest. Move quietly and avoid using bright lights or flash photography at night to minimize stress.
Interesting Facts
Koalas sleep up to 18-22 hours a day to conserve energy, as their diet of eucalyptus leaves is low in nutrition and toxic, requiring significant energy to digest. They have fingerprints similar to humans.
