The term 'Living in Trees' can be summarized by the word 'ARBOREAL', which means living in or among trees. ARBOREAL animals, such as monkeys, squirrels, and some birds, spend most of their lives in trees, either for protection from predators or to find food. ARBOREAL habitats provide a safe place for these animals to live and feed, and they often have complex social structures that are adapted to life in the trees.
