All primates, with the exception of the spider monkey, have five fingers and five toes on each hand and foot. Spider monkeys have four fingers on their hands and five toes on each foot.
A primate has excellent flexibility in its fingers and toes. This allows the animal to climb trees with ease, grasp branches and manipulate its food to get it to its mouth. The hands and feet have five flexible joints, and all primates have claws at the ends of their fingers and toes that can be used for digging, for scratching and even for protection against predators.
