So… Koalas, am I right?
Guess what? They’re not bears.
I know, shocking.
Class: Mammalia (Sub class Marsupialia)
Order: Diprotodontia (Bears are in the order Carnivora)
Family: Vombatiformes (yes, the same family as wombats)
So as you can see: bears and koalas only share a class, whereas koalas and wombats share a family.
KOALAS ARE NOT BEARS.
