Interesting about the koala

  • Koalas eat exclusively eucalyptus leaves and eucalyptus bark.
  • The total population of koala bears in Australia is estimated at 60,000 animals. Therefore, the Koala is classified by the World Conservation Union (IUCN) as an endangered species.
  • Koalas sleep more than 18 hours every day to save energy. The rest of the time is spent on feeding.
  • After birth, the cub crawls into the mother's pouch and stays there for at least 6 months.
  • Koalas are the most famous representatives of marsupials in addition to kangaroos.
  • The name "Koala" comes from the Aborigines and means "do not drink". That's only partially true. Although the koala absorbs a large amount of fluid through its food, it can not cover its entire fluid requirement.
  • Koalas have a poor immune system and are especially susceptible to virus and bacterial infections.
  • The repertoire of vocalizations is extensive. Koalas can bark (to signal mating readiness), scream (as a warning call to other koala bears), and buzz (when interacting with juveniles).
  • Brush fires are almost always synonymous with death for koalas, because they are too slow to flee from fire.
  • Koalas show a pronounced territorial behavior.
  • Koalas zoo-keeping is an immense cost because koalas only eat fresh and very specific eucalyptus leaves. For this reason daily fresh eucalyptus plants from Australia have to be flown in.
