They range from Senegal in the west to Tanzania in the east. |
Gorillas
live in west and central Africa, from Nigeria in the west to Rwanda
and Uganda in the east. |
Orangutans
are found in Asia, on the islands of Borneo and Sumatra. |
How
many types are there? |
Many
taxonomies exist for gibbons. It is generally accepted that there
are 16 species in four groups (genera): Hylobates, Hoolock,
Symphalangus, and Nomascus. |
There
is only one species of bonobo, Pan paniscus. |
There
is one species of chimpanzee, Pan troglodytes, and several
subspecies. |
There
are two species (each of which contain two subspecies): western gorilla,
Gorilla gorilla; and eastern gorilla, Gorilla beringei. |
There
are two species (and several subspecies): Bornean orangutan, Pongo
pygmaeus
Sumatran orangutan, Pongo abelii. |
Are
they endangered?* |
One
species is vulnerable, 11 are endangered, and 4 are critically endangered. |

Western
gorillas are critically endangered; eastern gorillas are endangered. |
Sumatran
orangutans are critically endangered; Bornean orangutans are endangered. |
What
do they eat? |
Gibbons
eat primarily fruit but also consume flowers, seeds, and leaves. |
Bonobos
consume mainly fruit but also eat seeds, flowers, leaves, and other
plant parts. |
Chimpanzees
mainly eat fruit as well as flowers, seeds, and other plant parts.
Some groups regularly hunt and consume meat. |
Gorillas
primarily consume leaves, stems, and roots. |
Their
diet primarily consists of fruit but also includes seeds, leaf shoots,
insects, flowers, and bark. |
How
big are they? |

12 (gibbon) - 28 (siamang) lbs
Females: 14 (gibbons) - 22 (siamang) lbs |
Males:
85 lbs
Females: 70 lbs |
Males:
90-132 lbs
Females: 70-100 lbs |
Males:
350-400 lbs
Females: 150-200 lbs |
Males:
175-200 lbs
Females: 70-100 lbs |
What
type of group do they live in? |
Gibbons
typically live in monogamous family groups consisting of a mated pair
and offspring, although groups with more than one adult female or
more than one adult male have been observed in some species. |
Groups
can range from 10-120 individuals; however, whole groups are rarely
together but instead consist of subgroups that can change membership
daily. Males tend to stay in their group for life while females leave
at sexual maturity. |
Groups
can contain 20-130 individuals and average 35 members. The whole group
is rarely found together but instead is usually found in subgroups
that may change membership daily. Males tend to stay in their group
for life while females leave at sexual maturity. |
Groups
may contain from 2 to 65 individuals (average 8-11). Gorillas have
close knit family groups that generally contain only one adult male
per group except in mountain gorillas. Males may be solitary. Both
males and females may leave their natal groups at maturity. |
Orangutans
are generally solitary, although they are sometimes seen in groups
of 2-3 if food is plentiful. |
