Aye-Aye (Daubentonia madagascariensis)

The aye-aye shown here lives on the island of Madagascar off the coast of Africa. It is a very specialized insect-eater. The aye-aye shares the primate characteristics of large eyes and good climbing abilities. The aye-aye, and most other prosimians, differ from monkeys and apes in having a moist area of skin on the nose. The Aye-aye is the only member of the family Daubentoniidae, and is considered to be the most bizarre of all primates. It is also the largest nocturnal primate in the world.

  • Slow Loris (Nycticebus)

    The Viet Nam War almost wiped out this species of loris, but recent years have seen significant growth in wild populations. Current threats to its survival include habitat destruction and capture for the pet and medicinal trade. Only about 13% of the remaining wild populations are found in protected areas.

  • Slender Loris (Nycticebus tardigradus)

    On the hand and foot, the second digit is reduced, and moves somewhat in the same plane as the thumb, making the hand and foot like pinchers. This needed for the slow methodical movement they employ. This species also has a relatively small tail. They have a dental comb for grooming. The eyes of the slender loris are fixed in a way so that it must move its head to achieve focus. The average body mass of an adult slender loris is between 227 and 355 grams (Petter and Petter-Rousseaux, 1979).

  • Mouse Lemur (Microcebes murinus)

    The gray mouse lemur is found on the Western and Southern coasts of Madagascar. The Western coastal forest is described as being deciduous with a relatively high rainfall and marked seasonality, and the Southern coastal forest is a semi-arid forest with low annual rainfall and a marked seasonality (Martin, 1972).

  • Marmoset (Callithrix)

    Marmosets are highly social primates and may be found in monogamous, polyandrous or small multimale and multifemale social groups. In most groups, however, only one breeding couple (the dominant or highest-ranking adult male and female) is usually observed. The older offspring and other group members assist in rearing the newborns of the dominant breeding female. Breeding female marmosets commonly give birth to twins, and one major benefit to them from group living comes from assistance in infant care. Infants born to subordinate females often do not survive infancy.

  • Wooley Monkey

    This monkey lives in large groups that split up to feed. During the day, it moves from one tree to the next in search of fruit and leaves. It hangs by its tail to reach food it cannot get with its hands. The woolly monkey does not come out of the trees often, but when it does, it walks in an upright position.

  • Indris (Indri indri)

    The indri is a large lemur weighing 7 - 10 kg (15 - 22 lb). It lives in montane moist forest up to 1500 m (4900'), where it is diurnal and arboreal. The indri's diet consists of leaves, flowers and fruit. It also occasionally eats dirt. The indri lives in small groups of from 2 - 5 individuals, usually consisting of an adult pair and their young. There is little overlap between neighboring groups. The female apparently is the dominant member of the pair. A single young is born every 2 - 3 years.

  • Galago (Galago)

    The lesser bush baby has thick, woolly, rather long and wavy fur which is silvery gray to brown dorsally and slightly lighter underneath. They have large ears with four transverse ridges that can be independently or simultaneously bent back and wrinkled downward from the tips toward the base. The ends of the fingers and toes have flat disks of thickened skin, which aid in grasping tree limbs and slippery surfaces. Their tongues have a cartilaginous protuberance underneath the fleshy tongue (like a second tongue) which is used in conjunction with the front teeth in grooming. The tarsus of the galago is greatly elongated to 1/3 the length of the shinbone, which allows it to adopt the hopping gate of a kangaroo. Galagos also have a greatly increased muscle mass in the hind legs, which also enables it to perform large leaps.

  • Proboscis Monkey

    The Proboscis monkey is heading towards extinction due to loss of habitat and hunting. The male species of this monkey weighs around 20 kg, has a pot belly and a huge red nose. Female Proboscis monkeys are much smaller and do not have a huge red nose. These monkeys are reddish-brown in color, with grey limbs and long white tails.

  • Common squirrel monkey infants have prehensile tails. Adults do not.
  • The black squirrel monkey has the smallest distribution - only 367 square miles of Brazil.
  • While most squirrel monkeys show no sexual dimorphism, Bolivian squirrel monkeys are sexually dichromatic - with black on the females and gray on the males.
  • Red-backed squirrel monkeys may have been introduced to Central America by humans.
  • 24% of golden-backed squirrel monkeys have tested positive for malaria.
  • Studies of the brain anatomy of black squirrel monkeys showed that the occipital lobe was devoted to auditory processing and was proportionally the most extensive of all primates except humans. This may be the result of the complex vocalization system utilized by squirrel monkeys.

  • Owl Monkey (Aotus)

    The Andean owl monkey is found in North-central Peru (Nowak, 1999). This species lives in elevation between 1200 and 2300 meters and also lives in humid lower montane cloud forests (Butchart et al., 1995).

  • Owl Monkey (Aotus)

    The Andean owl monkey has a grooming claw on the fourth digit of both feet. Members of the genus Aotus are the only nocturnal New World primate. The legs of this species are longer than the arms, which assists in leaping. The Andean owl monkey has large eyes, but lacks the tapetum typical of the nocturnal prosimians. The average body mass for this species is 1 kilogram, and no difference exists in body mass between males and females (Ford and Davis, 1992). This species belongs to the red-necked group.

  • Howler Monkey (Alouatta)

    The howler monkey is almost completely tree dwelling and is active during the day. It forages through the treetops for fruit and leaves. It usually lives in mixed-age and sex groups of up to 20 monkeys, which have one dominant male and a small number of younger males. The group territory is maintained by load roaring early each morning, with occasional roars and barks throughout the day. The monkeys may also continue to call throughout the night, and can be heard up to two miles away, even in the densest forest.
