They don’t have a single breeding season, but an individual spider monkey will wait about two to four years before giving birth again. Spider monkeys have a long gestation period, from seven to 7.5 months. ( These ultra-rare monkey twins have different fathers.) Like other primates, spider monkeys form consortships in which males and females pair up and leave the group for periods as short as a few days. It also noted that most trysts took place in secret. ![]() ![]() Spider monkey males and females are both known to have multiple sexual partners, but their reproductive behaviors are difficult to document, even in captivity, and weren't even observed until the 1970s.īut there have been some discoveries: A 2010 study on the black-faced spider monkey found that males must scramble to find and mate with the few receptive females in a single mating period. Baby spider monkeys also wrap their tiny tail around their mother's tail for security as they ride around on her back. Spider monkeys can let go with their arms and hang by their tail as they play and wrestle with each other high up in the tropical forest canopy. Males are likely on the move because they’re patrolling their borders and raiding other troops before returning to check on the females. A 2014 study of Mexican spider monkeys in Belize found that males and females spent their time differently, with females doing more eating and resting and males eating more ripe fruits and traveling. Within that group, smaller subgroups will often splinter off to forage. Spider monkeys are social, living in groups of up to 40 members. Between 50 and 90 percent of seed dispersal in tropical forests is done by animals. When animals eat fruit and nuts from trees and then go on their merry way, they eventually defecate the seeds and spread the tree species throughout the area. Spider monkeys are important seed dispersers for their rainforest homes. This animal’s diet consists mostly of fruits, plus leaves, nuts, seeds, and sometimes arachnids and insects. Red-faced spider monkeys are covered in longish black hair except for their bare faces, hands, and feet. White-bellied spider monkeys, which range from Colombia to Peru, for example, have a coat of hair that ranges from black to auburn with a light patch on their foreheads and a chin-to-belly swath of white-to-beige hair. It can support a spider monkey’s full body weight and allows them to hang onto branches, freeing their hands so they can climb, forage, and eat.Įach of the seven spider monkey species differs in geographic range and appearance, although they do share some physical traits and behaviors. The spider monkey’s tail is prehensile, which means “capable of grasping.” It is generally longer than the animal’s body and acts as a fifth limb-an adaptation to life in the tree canopy. (They also have thumbs but those are extremely short.) Their tree-to-tree locomotion, called brachiation, is how these swingers get around. Four long fingers on each hand help them grasp branches, too. There are seven species of these agile primates, which get their name from the way their long limbs and tails resemble spider legs as they dangle from branches and swing through the treetops. Spider monkeys are large New World monkeys that live in tropical rainforests from central Mexico in the north to Bolivia in the south.
