The Australian animal that is called a bear is not a bear is but a koala. They are called koala bears, tree bears or monkey bears by English-speaking settlers in the late 18th century only because they have bear-like features and behavior. They are mammals with the scientific name phascolarctos cinerus because they are pouched animals with grey coat and furry ears and they feed on eucalyptus leaves and barks. Koalas have unique characteristics that make them stand out from other animals such as:
1. They can live without drinking water if not necessary, because the water they get from the leaves they eat are sufficient enough for them.
2. They can eat eucalyptus leaves which are poisonous to most of the animals in the ecosystem as they have teeth that can grind these leaves into a fine paste. They can also digest the poisonous oil from eucalyptus because they have a special blend of bacteria in their digest tract.
