The Bonobo, Pan paniscus, until recently called the Pygmy Chimpanzee and less often, the Dwarf or Gracile Chimpanzee, is a
great ape and one of the two species making up the genus Pan. The other species in genus Pan is Pan troglodytes, or the Common
Chimpanzee. Although the name "chimpanzee" sometimes is used to refer to both species together, it is usually understood as
referring to the Common Chimpanzee.
The Common Chimpanzee (Pan troglodytes), also known as the Robust Chimpanzee, is a great ape. The name troglodytes, Greek
for 'cave-dweller', was coined by Johann Friedrich Blumenbach in his Handbuch der Naturgeschichte (Handbook of Natural History)
published in 1779. Colloquially, it is often called the chimpanzee (or simply 'chimp'), though technically this term refers
to both species in the genus Pan: the Common Chimpanzee and the closely-related Bonobo, or Pygmy Chimpanzee.
The Siamang (Symphalangus syndactylus) is a tailless, arboreal, black furred gibbon native to the forests of Malaysia, Thailand,
and Sumatra. The largest of the lesser apes, the Siamang can be twice the size of other gibbons, reaching 1 m in height, and
weighing up to 14 kg. The Siamang is the only species in the genus Symphalangus. The Siamang is distinctive for two reasons.
The Lar Gibbon (Hylobates lar), also known as the White-handed Gibbon, is a primate in the Hylobatidae or gibbon family. It
is one of the more well-known gibbons and is often seen in zoos.
Geoffroy's Spider Monkey, Ateles geoffroyi, also known as Black-handed Spider Monkey, is a species of spider monkey, a type
of New World monkey, from Central America and parts of Mexico. Its range also encompasses a small portion of Colombia. It
is one of the largest New World monkeys, often weighing as much as 9 kilograms. Its arms are significantly longer than its
legs, and it has a prehensile tail that can support the entire weight of the monkey, and is used as an extra limb.
