- Koalas are mostly nocturnal. Nocturnal animals are awake at night and asleep during the day. Koalas, however, sleep for part of the night and also sometimes move about in the daytime. They often sleep for up to 18-20 hours each day. - There is a myth that Koalas sleep a lot because they âget drunkâ on gumleaves.
Koalas can live around 10-15 years, and they have only a few natural predators, including dingoes, large owls, eagles, and goannas, which generally only target juveniles. The IUCN Red List classifies the koala as a species of least concern. However, they face several threats to their survival. Motor vehicle accidents and dogs are major causes of death for koalas, along with disease. The largest threat they face, however, is loss of habitat caused by land clearing/development, bushfires, and eucalyptus tree dieback.
