Oakland Zoo: Arabian Camel and Primates

Welcome to Oakland Zoo!

Feb 10

These photos show the Arabian camel and primates that we've seen at Oakland Zoo. The descriptions and animal "profile" pictures of Hamadryas Baboon, Tamarin and Vervet Monkey were retrieved from their website:

Dromedary (Arabian) Camel:

Single hump. Head and body length: 10 feet. Shoulder height: 6-7 feet. Weight: 1000-1500 pounds. Body is carried on long, slender legs ending in two toes beneath which is a broad, callous and elastic pad. Neck and head are both elongated. Upper lip is deeply cleft. Short tail. Eyes are heavily lashed. Ears are haired. Nostrils are slit-like. Coloration is fawn or beige. Coat is smooth and shorter than that of the Bactrian camel, but equally woolly.

The exact range of the Arabian Camel will probably never be known. The species exists only in the domesticated state today in Arabia and has been introduced into other regions of the world.

Tranquil atmosphere. Camels can be seen resting on the hill.


Height ranges from about 3-1/4 feet to 5-1/2 feet. Weight is from 99 pounds to 176 pounds. Arm-spread is 50% greater than height. No tail. Face bare, skin pink in infancy darkening to black in adulthood. Baldness is frequent in adults, typically a triangle on the forehead of male, more extensive in females. Hair color is black. Infants have white tail tuft and older males (20 or over) may develop grey back patch.

Western and Central Africa, north of river Zaire, from Senegal to Tanzania, from 14 degrees north to 10 degrees south. Humid forest, deciduous woodland or mixed savanna; presence in open areas depends on access to evergreen fruit-producing forest.


Largest of the lesser apes. Height: up to 3 feet. Weight: 20 to 45 pounds (Sumatran male is largest). Color: jet black, with long, profuse, somewhat shaggy hair. Face is naked with sparse stubble of moustache and beard. Armspread up to 5 feet. Forearm hair grows toward elbow as in great apes and man. Dark eyes, color vision and a throat sac inflatable to the size of the head. The toes are webbed between 2nd and 3rd toes. No facial fringe or tail.

Upper canopy of forested regions of Sumatra and the Malay Peninsula from 500 to 2500 feet.

White-Handed (Lar) Gibbon:

Body length is 44-63 cm (just under three feet). Average weight is 5.5 kg (14 pounds). Males and females are similar. Color is variable. They all have a pronounced and complete white face ring, white hands and feet. One square centimeter of skin has over 2,000 individual hairs (13,125 per sq. in.) compared to 900 hairs per sq. cm. for Old World monkeys. Arms are very long , fingers are long and hook-like, and thumbs are thin and somewhat reduced. No tail. Ischial callosities are present.

Middle and upper stories of deciduous monsoon and evergreen rain forest in southern Burma, Thailand, the Malay Peninsula, Sundaland to North Sumatra. (Also Indochina & Tenasserim?) Recently extirpated in Lancang county, China.

Hamadryas Baboon :

Length (without tail) 24 to 30 inches. Males weigh up to 40 lbs and are twice the weight of females. Males have massive features and a well-developed silver shaggy cape or mane. They have enormous canines, usually used in threat displays. Females and young are brown without mane. Infants are black. Tail arched gently backwards. Face is reddish-pink with a very long muzzle in the same line as the brain case. Ischial callosities are highly developed and bright red.

Inhabits semi-arid plains and rocky hill country in Ethiopia and Somalia in Africa, and Saudi Arabia and Yemen on the Arabian Peninsula. They are found from sea level to 2600 meters. They spend the night on rocky cliffs, sometimes foraging miles during the day but returning to the cliffs to sleep.

Squirrel Monkey:

HRL: 10-14 inches (26-36 cm). TL: 14-17 inches (35-42.5 cm). Weight: 1 1/2 - 2 1/2 pounds (.75-1.1 kg). Males are larger than females. Pelage short, thick, soft, and brightly colored. Skin on lips and around nostrils is black and almost devoid of hair. Most common coloration is white around eyes, ears, throat, and on sides of neck. Top of head is black to grayish, back forearms, hands, and feet are reddish or yellow with shoulders and hind feet suffused with gray. Thumb is short but well developed. Underparts whitish to yellowish, tail bicolored with black tip. Tail is not prehensile.

East of the Andes from Columbia and northern Peru to northeastern Brazil. Lives in virgin and secondary forests and in cultivated areas, usually along rivers and streams.

Cotton Topped Tamarin:

Tamarins are among the smallest of the primates. Head body length of this species is 17 cm (6 in.); Tail length is 25 cm (10-in.). Weight is a pound. The cottontop is strikingly marked with the long back fur dark brown, the fur on the underside pure white and the face black with a collar of rufous fur. The common name comes from the white crest which runs laterally across the head from ear to ear. Forelimbs are shorter than the hind limbs.

Tropical forests, open woodlands, and secondary growth of northwestern Colombia.

Vervet (Green) Monkey:

Stocky, green guenon. HBL 46-66 cm (18-26"). Weight 3.5-4.5 kg (7 1/4 to 10 pounds). Usually yellowish to olive green coat with white underparts and gray lower limbs. Face black with white cheek-tufts and browband. Both sexes have long, sharp canines.


The most widespread African guenon (there are up to 20 subspecies), occurring throughout the Northern and Southern Savanna, from Senegal to Sudan and south to the tip of South Africa. Adapted to practically all wooded habitats outside the equatorial rain forest. Being small and not a fast runner, this monkey cannot afford to venture far from the safety of trees. It is essentially an edge species and typically associated with riverine forest; in the dry savanna, they stay near the acacias. Colonies have been established on St. Kitts, Nevis, and the Barbados Islands in the West Indies-probably descended from pets.
