An example of an arboreal animal is a squirrel. Arboreal animals are animals that live in trees and have adaptations that allow them to move and live effectively in this environment. Squirrels are a classic example of arboreal animals as they are well-known for their ability to climb trees and live in the branches. They have strong hind legs, sharp claws, and a tail that helps them balance and maneuver in the trees. Squirrels use trees for food, shelter, and protection, and their arboreal lifestyle is a critical aspect of their survival.
