Black Spider monkey or A. paniscus are the largest New World monkeys; black-headed spider monkeys, the largest spider monkey, have an average weight of 24 lb. for males and 21.3 lb. for females.

Disproportionately long, spindly limbs inspired the spider monkey’s common name.

Their deftly prehensile tails, which may be up to 35 in. long, have very flexible, hairless tips and skin grooves similar to fingerprints. This adaptation to their strictly arboreal lifestyle serves as a fifth hand.

When the monkey walks, its arms practically drag on the ground. Unlike many monkeys, they do not use their arms for balance when walking, instead relying on their tails.

The hands are long, narrow and hook-like, and have reduced or non-existent thumbs. The fingers are elongated and recurved.

A. paniscus hair is coarse, ranging in color from ruddy gold to brown and black, or white in a rare number of specimens. The hands and feet are usually black. Heads are small with hairless faces.

The nostrils are very far apart, which is a distinguishing feature of Black spider monkeys.

The A. paniscus diets of consist of about 70 to 85 percent of fruits and nuts. They can live for long periods on only one or two kinds of fruits and nuts. They eat the fruits of many big forest trees and swallow fruits whole.

The A. paniscus feeds on a variety of foods and would be considered an omnivore. It will eat termites and grubs, but also feeds on supple leaves, flowers, mature seeds, tips of roots, fungi, berries and fruit. They may also consume honey, decaying wood or tree bark.

Studies show the diet of A. paniscus changes their reproductive, social, and physical behavioral patterns. Most feeding happens from dawn to 10 am. Afterward, the adults rest while the young play.

They have a unique way of getting food: a lead female is generally responsible for finding food sources. If she cannot find enough food for the group, it splits into smaller groups that forage separately.

The Red-faced Black Spider Monkey exhibits a fission-fusion society, associating with large groups of up to 30 individuals during the night, but choosing to spend the days travelling.

At night, they often sleep in large groups called bands. Bands typically consist of several females, with their respective young, along with a few males for protection. The only range size estimate was 630 acres, of which 540 acres had suitable habitat.

The A. paniscus has a gestation period of 226–232 days, is weaned after four or five years when it reaches sexual maturity, and has a life span of up to 33 years in captivity.
