Koala
Phascolarctos cinereus
Koalas are Marsupials, meaning they carry their
young in a pouch.
When the young [Joey's] are born, they are only the
size of a jellybean.
They have no fur and their eyes and ears are still
closed.
They attach themselves to a milk nipple to feed,
where it will it will remain for around six months.
Between 22 and 30 weeks of age the joey will feed
on 'pap' which is produced by the mother as a specialised form of faeces. This
allows the mother to pass on micro-organisms to the joey which are essential for
the digestion of eucalyptus leaves.
The joey will then ride on its mothers back until about 12 months old when it
can take care of itself.
Koalas have two thumbs on their front paws which help them to grip the tree and
their food and to help them climb. On the hind paw, the second and third toes
are fused together to form a' grooming claw'.
Koala's sleep a lot to conserve energy as they
store little or no fat in their bodies.
The fur on the koala's bottom is dense to provide a cushion for the hard
branches it sits on. It is also 'speckled' in colour to make the koala hard to
spot from the ground. The male koala has a dark, scent gland in the centre of his chest which he
rubs on tree's in order to mark his territory.
