How high do koalas live?

Koalas don't really "live" at a specific height. They live in eucalyptus trees, and the height they are at depends on the specific tree they are in and what they are doing.

Here's a breakdown:

* For feeding: Koalas are most often found in the canopy of the eucalyptus tree, which is the upper part of the tree where the leaves are. This can be anywhere from 5 meters (16 feet) to 30 meters (98 feet) high depending on the size and type of tree.

* For sleeping: They might sleep lower down in the tree, closer to the trunk, where it's safer and they're less exposed.

* For breeding: Females often build their nests in the lower branches of trees for birthing and raising their young.

So, there's no single answer to how high koalas live. They are arboreal animals that spend their lives in trees, moving up and down depending on their needs.
