Lemurs are prosimian primates endemic to the island of Madagascar. They spend most of their time in the trees, where they find their food, play, and rest. They primarily eat fruits but also seeds, leaves, and nectar. After breeding, lemurs build their nest in a tree. After that, the mother hangs hairs from her body on the nest to cushion the nest for when the babies are born. The young leave the nest after three weeks, but only after seven weeks are they able to independently move between the trees.
