Usually all the time
None at all. The koala is not a bear; nor does it live in Africa; nor can it survive in grasslands.See the related question for what adaptations a koala has.
Do NOT tend to your hamster's babies. Leave all that work to the mom. Don't touch them either, or the mom will smell your scent on her babies and eat them.
Sometimes they will, but most of the time the babies are black. My Molly Fish just had babies and all but one was black. The other one was brown. So, yeah. They can be brown.
No. Young koalas are called joeys, just like the young of all marsupials.The term 'cub' is reserved for bears, and koalas are notbears, despite the misnomer of "koala bear" often being applied.
Koalas, which are not bears at all, usually have just one young (joey) per year.
OF COURSE. All animals have to reproduce in order to survive.
First of all, the koala is not a bear: it is a marsupial. Koalas do not have white skin: they have ash-coloured grey type of skin tending to pink, beneath their thick fur.
A koala is not at all related to a raccoon.
Not all babies will survive until they can reproduce. Thus, natural selection allows only the strongest to live and reproduce, eliminating the weaker babies to make more weak babies.
Yes. Like all marsupials, koala joeys are tiny, hairless, blind and completely helpless, unable to survive outside of the mother's pouch.
One living factor for a koala is that Eucalyptus trees provide the leaves which the Koala's love to eat and it provides all the Koala's Energy.
There is no such animal as a "koala bear". If there were, then there would be no single answer to this question.Kangaroos, koalas (not bears) and possums all belong to the mammal group known as Marsupials.
