The black-headed spider monkey is a New World monkey that hails from Central and South America. They prefer humid forests, cloud forests, and dry forests. There are 2 subspecies of these spider monkeys: the black-headed and the brown-headed spider monkey. Due to hunting, habitat destruction, and human interference, these cool monkeys are sadly listed as Critically Endangered by the IUCN and their numbers are decreasing.

First the Stats… Scientific name: Ateles fusciceps Weight: Up to 15 lbs. Length: Up to 19 inches, plus up to a 33.7 inch tail Lifespan: Up to 24 years

Now on to the Facts! 1.) These monkeys are diurnal (active during the day).

2.) Like all spider monkeys, they are predominantly arboreal (spend their lives in trees).

3.) Forming large fission-fusion groups of up to 100 individuals is common. These groups are comprised of multiple males and females.

4.) They are extremely agile climbers able to walk upright on branches.

5.) A group of spider monkeys is called a barrel, cartload, tribe, troop, or wilderness.

But wait, there’s more on the black-headed spider monkey! 6.) These monkeys use all 4 limbs to navigate the tree tops.

7.) Communication consists of a high frequency whinny, body language, and possible scent marking.

Did you know…? When utilizing brachiation (locomotion via swinging from branch to branch) these monkeys can reach distances of up to 30 feet with a single leap!

8.) Like many other New World monkeys, they are primarily folivores (eat leaves) and frugivores (eat fruit). The consumption of ripe fruits and leaves is supplemented with occasional seeds, nuts, insects, and even eggs.

9.) It is unknown if they are polygynandrous (males and females mate with multiple partners) or polyandrous (1 female mates with several males).

10.) Females produce a single infant approximately every 2 – 3 years.

But wait, there’s still more on the black-headed spider monkey! 11.) Gestation (pregnancy) lasts up to 232 days.

12.) These frisky monkeys can breed at any time of the year.

Did you know…? When various troops meet, they will often greet each other via hugging.

13.) Their tails are prehensile (used as a 5th appendage).

14.) Jaguars , cougars , ocelots , harpy eagles , and large snakes all prey on these monkeys.

15.) This species of monkey is also characterized by having only 4 fingers.

A folivore primarily eats leaves. They seldom, if at all, eat anything else. These types of critters typically have a very slow metabolism and also move slower to save energy, as their diet doesn\'t provide much nutrition.

Some animals that fall into this category are: koalas , sloths , and pandas , to name a few.'); toolTips('.classtoolTips30','

An animal that falls into this category is active during the day. Animals that fit this description typically use sight for hunting prey. Others, like turtles , are active during the day as they need the sun\'s rays to aid in the production of vitamin D, which is needed to help process calcium and prevent metabolic bone disease. Hummingbirds rely on the sun as most of the nectar they gather comes from flowers that are open during the day. Cows , dogs , elephants , butterflies , and squirrels , for example, are diurnal.');
