Meet our featured animal: the koala!
Friday, September 30 is Save the Koala Day!
Here are five fun facts about koalas:
- Koalas are not bears, despite the common phrase, “koala bear”. Koalas are actually marsupials, like kangaroos and wombats. This means female koalas have pouches where their young stay until fully-developed.
- Koalas are well-adapted to sitting in trees. They have a curved backbone and two fewer pairs of ribs than most mammals (11 instead of 13) creating a curled skeletal structure that fits well into the forks of branches.
- Although there are 600 types of eucalyptus trees, koalas generally limit their diet to two or three favorite kinds.
- Koalas have a special kind of bacteria in their stomachs that break down the fiber and toxic oils in eucalyptus leaves. This bacteria is passed down from mother koala to joey via a substance the mother produces called pap.
- A koala’s pregnancy lasts 35 days. When the joey is born, it is only 2 cm (less than an inch) long. Although hairless and blind, the newborn uses its strong forelimbs to climb from the birth canal into the mother’s pouch.
