Koalas are endemic to Australia, meaning they are not found in the wild anywhere else in the world. There may be a few US zoos which have permission to have koalas, but regulations controlling the movement of koalas outside of Australia are very strict.
Koalas may not be kept as pets anywhere in the world. Even zoos must prove they are qualified to keep them.
It is unlikely that koalas could survive in America. Koalas require just a certain few species of eucalyptus trees for their food, and the required genus of eucalyptus are not found in America.
Koalas
Koalas are not bears. Koalas are indigenous to Australia.
KOALAS
No. Koalas do not live in North America at all. They are native to Australia alone, and are not found nywhere outside of Australia.
If the question is asking in which states it is legal to keep a koala, the answer is none. Koalas are native marsupials of Australia, and although they are not classified as 'endangered', they are nonetheless protected by law, and not permitted to be kept as pets anywhere in the world.
No, tigers cannot eat koalas because koalas live in Australia and tigers live in Asia and South America. If they inhabited the same continent, there is every chance that tigers would eat koalas, as koalas range from tree to tree, and do spend some time on the ground.
No, koalas, unlike some mammals with similar characteristics shared between the two continents, are only native to Australia.
No, koalas do not live in the deserts of Australia. They need eucalyptus trees for food and they do not grow in the deserts.
Kangaroos do not have fleas unless they have been in contact with domestic pets. Kangaroo rats of North America, which are not remotely related to kangaroos, are more likely to have fleas.
Adult koalas are simply called koalas.
Yes they are legal in the US. When my husbands family moved to America his mom and dads marriage was recognized by America and it was legal.
