LEARN ABOUT: Koala, Australia
(Plascolarctos cinereus)
Koalas
are are not bears.
They
are arboreal marsupials, mammals that live in trees and
carry
and suckle their joeys (babies) in a pouch on mom's belly for up to six
months. Their gestation period is only 35 days.
They
grow to be about 30 lbs. and two feet long.
Koalas
that live near man, are stressed by loss and contamination of habitat and
thus, food sources. Four thousand koalas are killed each year by cars and
domestic dogs. Average life span is a mere three to four years.
In
the wild, koalas have many more enemies, goannas, dingoes, owls, eagles, and
pythons, but can live for as many as 15-17 years.
“Koala”
is an Aboriginal word that means “no drink." Their diet consists almost
entirely of the leaves from eucalyptus trees. These leaves provide them with
enough water so they do not need to descend to the dangers of ground level.
Sadly,
koalas are animals with extremely small brains. The two halves of their
brains are the size of small walnuts. These two halves are not connected to
each other or to the skull bones and sit on the brain stem in liquid that
fills 40% of their brain cavities.
In
a 24 hour day, they sleep for 19 hours, eat for 3 hours and
for
the other 2 hours...
