NATURE OF HUMAN NATURE
Have you ever heard someone refer to a koala as a "koala
bear?" Well, like bears, koalas are mammals, and they have round, fuzzy
ears and look cute and cuddly, like a teddy bear. But koalas are not bears.
They are members of a group of pouched animals called marsupials. Marsupials
include kangaroos, wallabies, wallaroos, wombats, possums, and opossums. Koalas
look soft, but their fur feels like the coarse wool of a sheep. They also seem
cuddly, but koalas are wild animals and don't make good pets.
Koalas
are native to southeastern and eastern Australia, living in forests of
eucalyptus trees. They are basically sedentary animals that need to sleep a lot
to give them time to digest their food. Being on the ground all the time would
be a disadvantage, because predators could catch them easily. Instead, they
adapted to live way up in eucalyptus trees, rear end firmly planted in the fork
of branches, so they can chew leaves and nap all they want to without feeling
threatened.
Eucalyptus
forests are home, shelter, and food for koalas. The animals are built to live
in the crooks of branches: koalas have a reduced tail, a curved spine, and a rounded
rear end. But they do travel on the ground when necessary, to get from tree to
tree or to a new area. On hot days, koalas select the coolest trees and the
coolest locations in those trees (against the trunk and other low, shaded
branches) for resting. On cooler days, koalas are more likely to rest farther
away from the trunk where they can absorb heat from the sun.
Koalas
have few natural predators, although sometimes a dingo or large owl can take
one. The most common direct causes of koala deaths are from motor vehicles and
dogs. Koalas are definitely safest high up in trees.
