Lemurs

Lemurs are located in Madagascar and nearby Comoro islands. They have large eyes, long hind limbs, foxlike faces, and most of them have long bushy tails. Compared to monkeys, lemurs are less intelligent and rely on their keen sense of smell over vision, and many are adapted for nocturnal life with their light sensitive eyes. Some common traits among lemurs are a moist nose tip, a noninvasive placenta, a unique comblike set of lower teeth, and a specialized claw on their second toe for grooming. Lemurs spend most their time in trees eating fruit, insects, buds, leaves, and small birds and their eggs. 

Woolly Spider Monkey

The Woolly Spider Monkey is an extremely rare primate that only lives in the Atlantic forests of Southeastern Brazil. It is also the largest monkey in South America with thick fur, a heavy body, a protruding abdomen like standard Woolly monkeys, and long limbs with reduced thumbs that resemble spider monkeys. The woolly spider monkey is 45-63 cm long, with 65-80 cm prehensile tails that are used for climbing and swinging. They are active day and night in the treetops and forage for leaves, seeds and fruit. They are more related to woolly monkeys than spider monkeys and are considered critically endangered as their forest habitat is extremely fragmented.

They have arms and legs that are about the same length, fur that is generally a shade of brown or black, a doglike muzzle that is rotund in profile, and their tail size varies between species of long, moderate, short or absent. Size also varies between species in a range of 41-70 cm long, and 2.4kg-18kg in weight. Macaques live in troops of varying size with dominant male and females ranked off of genealogical position. They are also omnivorous and possess large cheek pouches that can carry extra food. 

Orangutan

Orangutans are found in the rainforests of the Asian islands Borneo and Sumatra and possess cognitive abilities comparable to gorillas and chimpanzees, which are the only primates more closely related to humans. Orangutans are not as strong gorillas but are larger than chimpanzees. Males can measure up to 4.3 ft tall and 285 pounds, while females are shorter and weigh 82 pounds or less. They are covered in sparse red hard and have brownish or dark tan skin. Orangutans spend most of their time the trees and their day consists of sleeping and feeding. They predominantly eat ripe fruit, but they also consume 400 other different types of food including invertebrates, and in rare occasions, meat.
