EXTANT PRIMATES There are more than 350 species of primates ( a lot of them are actually
endangered ) , varying in size from the pygmy mouse lemur (weighing about an ounce) to gorillas
(males can weigh up to 600 pounds). Most live in the tropics or subtropics, and most depend on
forests for their survival. Primates share characteristics—such as five-fingered hands with opposing
thumbs, forward-facing eyes, and color vision—but they do vary greatly, especially from prosimian to
monkey to ape.

roots and other plant parts. They will also occasionally eat invertebrates. Due to loss of habitat to
human farming, gelada populations are declining

Baboon is at home in the rainforests. Although they are true quadrupeds, their opposable thumb and
flexible clavicles allow them to be at home in the trees, where they often are found at night. Their
brilliantly colored face distinguishes them from other baboons and primates. Their large head and
prominent fangs (especially in males) make them formidable adversaries. They are omnivorous, eating
fruit, roots, insects and reptiles.

Anthropoid Evolution
Many of the interesting traits and functions that we study in primates are housed in the skull: the brain, facial expression
vocalization, to name a few. Because of its importance to primates such as ourselves, evolution of skull form and functi
question of evolutionary anthropology. The fact that we share so many aspects of our development and our genetic ma
allows us to learn much about human evolutionary history by looking at non-human primates.

and a lemur (a prosimian).
Baboons and other living monkeys, as well as apes and humans, are anthropoid (literally, “humanlike”) primates. In addition to being numerous and easily adaptable to captivity, baboons (and their
ancestors) are well-represented in the fossil record. All of these traits make them an excellent model
species for scientific research. Additionally, the baboons are part of a radiation of primates—the
papionins—that includes many other closely-related species that exhibit a range of skull shapes. For
this reason, the papionins are a useful group of primates with which to model the differences in skull
form that we find in the fossil record of hominids (humans and their closest ancestors). In this project
we take advantage of similarities between hominids and papionins to learn about how certain features
(like small teeth and a big brain) have been selected for during human evolution.

baboon-like species. Left to right: arboreal mangabey, mandrill, gelada baboon, olive baboon.

The VERVET MONKEY , also called the green, the grivet and the Tantalus monkey, is native to Africa
and is the most common of the savanna monkeys. The vervet monkey's physical description can be
summed up as a medium sized primate approximately 40 to 60 cm (15.7" to 23.6") in length with a tale
measuring 30 to 50 cm (11.8" to 19.6"). This species can weigh between 3 and 5 kg (6.6 to 11 lbs).
The vervet?s coat is silky and color varies from silver to yellow to reddish to green depending on
geographic location. Vervets are characterized by their black face and white brow. This species is
sexually dimorphic with males being nearly .5% larger than females. Vervets possess elongated
whiskers that are usually white or pale yellow in color and can differ in length between individuals. On
of the defining characteristic of this species, and the source of its name, is the greenish color of the
upper parts of the face. This coloration is an illusion caused by individual hairs with black and yellow
strands. Male vervets can be clearly identified by their blue scrotum.
Chlorocebus (formerly known as Cercopithecus) aethiops, has a large geographic range and can be found
throughout central Africa and southward over much of the continent. Vervets are both terrestrial and ground
dwelling. Their habitat consists of savanna grassland as well as scrub forest. However, and unlike many other
African primate species, vervets are very adept at traveling on the ground and tend to inhabit open grassland
areas more than forests.Vervets tend to dwell close to a lakes or rivers due to their need for daily water. This
species is typically diurnal, being active and feeding mostly during the day. Vervets sleep in trees at night.
Vervets, like many primate species, are social animals. They travel in small groups, called troops that may
number only a few to as many 140 individuals. Although aggression within a troop is rare, vervets are highly
territorial and often clash with surrounding troops. Unlike many other monkey species, vervets tend to have mutimale groups, with a hierarchy of the strongest males at the top. Like many primates, the vervet possess a wide
range of facial gestures for communication as well as vocal calls. Males will compete for mates with a complete
system of display that includes baring teeth, jaw movements and aggression. Vervets are polygamous with
females typically having only a few mates in their lifetime and males possessing numerous breeding partners.
Grooming is a common social behavior in this species and can be used in courtship. During the breeding season,
which can be year round, the female's gentalia will swell, alerting the males when they are in heat. Dominant
males will often perform a "red, white and blue" genital display to attract females; the colors referring to the males,
penis, belly hair and scrotum.
Gestation for this species runs approximately 175 to 200 days. Vervets are small at birth weighing only 300 to
400g (10.5 to 14 ounces). Females generally are responsible for raising the young and will often share maternal
duties with other females within their social groups. The young will cling to its mother belly for roughly three
weeks. Vervets reach sexual maturity at 2.5 years and live 10 to 15 years in the wild and up to 25 years in
captivity.
The vervet monkey is an omnivore with a diet that includes insects, plants, and vertebrates. However, this species
primarily eats fruits. As a frugivore, this species plays an important role in the ecosystem as a seed disperser.
Vervet monkeys serve as prey for leopards, snakes, raptors, baboons and humans.
The vervet monkey delineated from the human evolutionary lineage over 50 million years ago. However, due to
their generally close biological design, this species is often used by humans as a research subject in medical and
commercial studies. Vervets are considered a pest by many human inhabitants within their range. This species, in
addition to possessing little fear of humans, can climb and jump well making it a major nuisance to human crops,
gardens and plantations. Due to over hunting and habitat destruction, the international organization CITES, the
Convention on International Trade in Endangered Species of Wild Fauna and Flora, has classified the vervet
monkey as Appendix 2. Appendix 2 applies to species that are not necessarily threatened with extinction, but may
become so if not regulated. This species has been thought to have been the original host for the HIV AIDS virus.
It is thought that humans first contracted a mutated form of the virus from eating undercooked or raw vervet
monkeys during religious practices.
Vervet-Green-Monkey.jpg
Green Vervet Monkey (Chlorocebus pygerythrus). The Vervet Monkey inhabits savanna and
mountains up to 4000 m. The Vervet Monkey is mainly frugivorous, but it also supplements its diet with
a variety of other foods, including leaves, seeds, insects and small rodents. It sometimes lives in

more than 60% of its day on the ground foraging for food and socializing, but sleeping and searching for food in the
trees. It lives in groups of 5 to 25 animals.
COLOBUS
ColubusBlackAndWhite.jpg
King Colubus, or Western Black-and-White Colobus Monkey (Colobus polykomos). Found in lowland
and mountain rain forests in a region stretching between Gambia and C�te d'Ivoire within Africa. It
eats mainly leaves, but also fruits and flowers. Though it is arboreal, it eats primarily on the ground. It
lives in small groups consisting of 3 to 4 females and 1 to 3 males, plus their young.
Male skull.
Colobus monkeys are native to central Africa. This species gets its name, due to their reduced thumb
size, from the Greek word colobus, meaning mutilated. However, this "mutilation" allows the colobus to
move more freely through the tree-tops than other African monkeys. Colobus are unique in that their
digestive system allows them to eat certain leaves and unripe fruit containing toxins that most other
monkeys avoid

Feeding in troops that contain both males and females of various ages, the Hanuman langur dines
primarily on leaves and other plant parts. This diurnal species sleeps in shady groves during the hot
midday hours. This langur is considered sacred in parts of its range
Douc-Langur.jpg
Red-shanked Douc Langur (Pygothrix nemaeus). The douc is an arboreal and diurnal monkey, eating
and sleeping in the trees of the forest, and is probably the most colourful of all mammals. The Redshanked Douc is thought to be found only in north and central Vietnam and Laos. Doucs are found in
a variety of habitats: from lowland to mountainous terrain up to 2,000 m (6,600 feet), in deciduous,
primary rainforest and secondary rainforests, in the mid to upper levels of the canopy.
The Douc Langur is native to the rainforests of Viet Nam, Laos and Cambodia in Southeast Asia. Their
Diet consists of leaves, fruit, and flowers. This brilliantly colored species is arboreal, living in the
highest canopy of the forest. Due to excessive loss of habitat, over hunting, collection for the pet trade
and environmental disruption attributed to the Viet Nam War, this species is now listed as endangered
Purple-Faced-Langur.jpg
Purple-faced Langur (Trachypithecus vetulus). Native to Sri Lanka. This is a long-tailed arboreal
species, mainly brown with a dark facemask and paler lower face. The loud barking call, particularly of
the highland form, can be mistaken for the roar of a predator such as a Leopard. This was once a
common species, which was found even in suburban Colombo and in the wet zone villages, but rapid
urbanization has taken a toll on the numbers of these monkeys.
The Purple-faced Langur is native to the primary and secondary forests of Sri Lanka. They live a
diurnal, arboreal life feeding on fruit, leaves, seeds, flowers and insects.
The Brown lemur is a diurnal, arboreal species, spending most of its time in the upper
canopy layers and rarely descending. The diet of the Brown lemur consists mostly of fruits, flowers,
and leaves. This and four other species were recently split from the genus Lemur to create the genus
Eulemur.

Madagascar. Females are slightly larger than males.
The Ruffed Lemur is the larges species of lemur. Like most lemurs, it is crepuscular, being most active in the morning
and evening.
The Ruffed Lemur lives an arboreal life eating mostly fruits and occasional insects.
mouse lemur.JPG
Mouse lemurs, from Madagascar, are the smallest primates in the world. The gray mouse lemur
Microcebus murinus, has a body length less than 5 inches long. Mouse lemurs are found throughout
the dry deciduous forests and spiny deserts of south and west Madagascar.
The ring-tailed lemur is native only to southern Madagascar. This diurnal species eats
mostly fruits, leaves and occasionally insects. The ring-tailed lemur lives in groups numbering from 5
to 25 individuals with little or no established hierarchy. In recent years, ring-tailed lemur populations
have declined due to loss of habitat
LemurRingtailed.jpg
Ring-tailed Lemur (Lemur catta). The Ring-tailed Lemur is a prosimian which eats mostly fruit, but will
also eat leaves. It is found in the southwest of Madagascar and ranges further into highland areas
than any other lemur.
Lemur Cata
Galago bushbabies
The three species of
are native to parts of Africa. Bushbabies feed
on fruits, insects and small vertebrates. The bushbaby is a nocturnal primate. Their large eyes allow
for more light absorbing rods, and thus, better night vision. Like an owl, the bush babies eyes are fixed
in their sockets. To compensate for this, the bushbaby can rotate its head nearly 180 degrees.
Bush-Baby.jpg
Bush Baby (Galago senegalensis). Bush Babies have large eyes, giving them good night vision,
strong hind limbs, and long tails, which help them balance. Their diet is a mixture of insects and other
small animals, fruit, and tree gums
TamarinGolden.jpg
Golden-headed (Lion) Tamarin (Leontopithecus chrysomelas). The Golden-headed Tamarin is
endemic to Brazil. It is found only in the lowland and premontane tropical forest fragments in the state
of Bahia, and is considered to be an endangered species.
The Golden-headed lion tamarin, named for its orange mane-like head pelage, is native to the
rainforests of Brazil, South America. This small arboreal primate lives high in the canopy where it
feeds on various insects and fruits. Wild populations of this species have drastically declined due to
deforestation. It is estimated that as few as 200 individuals remain
Cotton-topped Tamarin (Saguinius oedipus). Known as the Pinch� Tamarin, this Tamarin weighs less
than 1lb (0.5 kg). It is found in tropical forest edges and secondary forests where it is arboreal and
diurnal. The Cottontop Tamarin eats fruit, insects, new leaves or buds, small lizards and nectar. It is
called "Liszt Monkey" in German due to its supposed resemblance to the composer Franz Liszt.
Slow-LorisMale.jpg
Sunda Slow Loris (Nycticebus cougang). This slow moving strepsirrhine primate has large eyes that
point forward, and ears that are small and nearly hidden in the fur. Its tail is a mere stump. The Sunda
Loris is a diurnal and arboreal animal that prefers the tops of the trees. Also, they have slow,
deliberate movements and a powerful grasp that makes them very difficult to remove from branches.
Slender lori
The slender loris is a small, nocturnal primate native to the tropical rainforests of Southern India and
Sri Lanka. This species is arboreal, spending most of its life in trees. The slender loris is primarily
insectivorous, but will also eat slugs, leaves, flowers, eggs and nestlings. Due to habitat destruction
and supposed traditional medicinal use, slender loris populations have greatly declined
Perodicticus potto /Family: Lorisidae
This species is native to the
tropical forests of central and western Africa. The potto is a small prosimian that feeds on fruit and
