GIBBON
			Phylum: Class: Order: Family: Chordata Mammalia Primates Hylobatidae

Gibbons, the smallest of the apes, have long arms, which may be
one-and-a-half times as long as the legs. They travel through the trees by
swinging by their arms, often making leaps of 30 ft. (9 m) or more between
the branches. They are the only apes to walk upright habitually, most
reaching a height of about 3 ft. (90 cm), though the tallest, the siamang,
stands up to 4 ft. (120 cm) high.

Six species of gibbon exist. The siamang lives on the Malay peninsula and
in Sumatra, and the dwarf siamang lives on small islands west of Sumatra.
Both species are completely black. The concolor gibbon occurs in Laos,
Vietnam, and Hainan. The hoolock gibbon is found in Burma. The black-capped
gibbon occurs in Thailand. The males of the last three species are black,
and the females are fawn. The sixth species, the Lar gibbon, is found in
Thailand, the Malay peninsula, Sumatra, Java, and Borneo. Gibbons live in
small groups, often consisting of a pair, which mate for life, and up to
four offspring. The group occupies a small territory and the animals hoot
and call noisily each morning to let other groups know they are there. The
gibbons' main food is fruit. They breed year-round and the gestation period
is seven months. They have been known to live as long as 25 years.
