Contrary to popular belief, koala bears are neither cuddly nor kind. These tree creatures may be deceptively adorable but they’re known to chase and attack when provoked, and are likely to claw your eyes if they feel threatened. The human population mistakes them for bears, but they’re actually marsupials – close relatives of the kangaroo and the wombat. Marsupials are not meant to be coddled and pet, even though it’s hard to resist using baby talk when you see them at the zoo. Perhaps their extra set of reproductive organs is the reason for their startling aggression.
