4 - Tree Kangaroo
Most people don't think of kangaroos as arboreal, but the tree kangaroo is very much at home in the canopy, only occasionally venturing to the ground for food or to move to a new tree. Compared to ground-dwelling kangaroos, tree kangaroos are stout with strong claws to help them climb. Their long tails are not prehensile, but act as a counterbalance as they move along branches. Unlike other kangaroos, tree kangaroos can move each back leg independently, which gives them the agility they need to move from branch to branch.
