Spider Monkey


Spider monkeys have slender bodies with long, thin limbs and are usually all black, but occasionally there are flesh-colored rings around the eyes and white chin whiskers.  They have exceptionally long tails in relation to their body length, which averages from 16-21” with the tail being 28-34”.


Spider monkeys live in large, relatively unstructured communities of up to 100 individuals, but there is great variation in numbers with larger groups usually broken up into smaller groups.  The most cohesive units are female groups with offspring in an otherwise loose construction.  Social grooming is of relatively low value but demonstrates rank order within the group.  Spider monkeys are diurnal, so they spend the majority of the early morning hours foraging for food.  Although locomotion is basically quadrepedal, they are capable of swinging below branches by means of arms and tail.  There is usually a single birth for each successful breeding, and the youngster is carried on the mother’s abdomen for about four months, and then later switched to her back.  Infants use their prehensile tail to hold onto mother’s tail for more stability.
