Arboreal Animals

Arboreal animals : are those animals that spend most of their life on trees. They feed, travel, play, and sleep on trees. They prefer to grow their young ones on the trees, which is a difficult task because the newborns are always prone to fall on the ground from height. However, they have adapted themselves in such a manner that these animals can now easily live on such heights. Examples of such animals include chameleons, lizards, green tree pythons, tree snails, koalas, squirrels, cats, monkeys, parrots, sloths, and a variety of insects. Leopards and goats are also considered arboreal because of their excellent ability to climb the trees. Leopards can carry their kills to the top of trees to avoid other predators and scavengers.
