THE KOALA
Physical description
The koala is a species of marsupial. It measures
between 61 and 85 cm and weighs between 4 and 14 kg. His corpulence depends on
the region in which he lives. In colder areas, koalas are larger, while in
places where there is little rain, they are smaller.
The thick fur of the koala is gray over most of its
body, and white on the ends of the ears. His head is big compared to his body,
with big round ears. His big black nose, very sensitive to odors, provides him
with a lot of information about the world around him: the quality of his food,
the presence of predators, females, etc.
The koala has no tail but its morphology allows it to
keep a good balance when it is on the branches. Its four limbs are short and
end with five fingers with pointed claws, allowing it to easily grip the trees.
As with all marsupials, the female has a ventral pocket.
His place of life
Koalas are only found in Australia on the east and
south coasts. They love moist forests and spend most of their time in the
trees. However, when the trees are distant from each other, they can move on
the ground.
His diet
Koalas are herbivores and consume only leaves, barks
and eucalyptus fruits. They rarely drink and cover their water needs with
eucalyptus leaves.
His reproduction
Koalas are sexually mature around the age of 3. The
breeding season runs from October to April. The dominant male mates with
several females. The gestation lasts only a month and the little one is born is
hardly bigger than a pea. He is, however, provided with claws which he will use
to climb in the ventral pocket of his mother, where he will be breastfed for 6
to 7 months.
Gradually, breast milk will be replaced by a kind of
porridge, consisting of partially digested eucalyptus leaves. As the body
grows, the baby will come out of the ventral pouch to learn how to feed
himself, but will not be weaned until he is one year old. At the age of 18
months, if the mother has a new pregnancy, she will hunt her offspring so that
she can start her own territory. Otherwise, he can stay with her until the age
of 3 years.
His life expectancy
The koala can live between the ages of 13 and 20, with
females having a longer life expectancy than males.
The cry of koala
Koalas emit different types of sounds depending on the
situation. When stressed, they cry out like a human baby. During the breeding
season, males can be heard growling loudly to attract females and intimidate
other males. Females and their young, for their part, affectionately exchange
squeaks and clicks.
Particular signs
Koalas spend most of their day sleeping, and the short
time they are awake, they stay still, busy eating and cleaning themselves.
