Types of Apes

Types of Apes

Types of Apes: There are two main types of apes: “lesser apes” and “great apes“. Lesser apes include mainly all gibbon species, whereas the Great apes include orangutans, gorillas, chimpanzees, and bonobos.

Great apes and humans belong to the same primate group called hominoids despite differences in limb length and jaw shape; their bone structure similarities can be noticed. However, apes and humans are not directly related.

Humans belong to a separate division of the hominoid family called the hominids. This group includes modern humans (Homo sapiens sapiens) and our direct ancestors.

Recent genetics research indicates that the hominid and ape lineages may have diverged about 7 to 9 million years ago^[1].

Here are two main kinds of apes namely:

Lesser Apes
Gibbons (also called lesser apes) belong to the family Hylobatidae, and there are 20 discovered species. Gibbons live in sub-tropical and tropical rainforests of Bangladesh, India, China, and the Indonesian islands. All gibbons are tailless and smaller in size when compared to Great apes.
Great Apes
The Hominidae family members are great apes or hominids. This taxonomic primate contains four genera, namely Pongo (Orangutans), Gorilla (East and West Gorillas), Pan (Chimpanzees & Bonobos), and Homo (modern humans).
- Orangutans
  
  These great apes are native to Indonesia and Malaysia’s rainforests but are found only in Borneo and Sumatra islands. There are only 3 known species of orangutans under the genus Pongo.
- Gorillas
  
  Gorillas are plant-eating primates, mostly ground-dwelling great apes found in equatorial African tropical forests. The genus Gorilla comprises two species: the eastern and western gorilla. The DNA of gorillas is more similar to that of humans. So, gorillas are the closest relatives to humans after Chimpanzees and Bonobos.
- Chimpanzees
  
  The chimpanzee (also called chimp or common chimpanzee, or robust chimpanzee) is another great ape found in the forest and savannah of tropical Africa. Chimpanzees are the closest relatives to humans.
- Bonobos
  
  The bonobo (also called the pygmy chimpanzee) is an endangered great ape and another species in the genus Pan. Bonobos were initially thought to be a subspecies of chimpanzees due to their physical similarities, but they are now a separate species.

Gibbons

Abbott’s Gray Gibbon

Species Name: Hylobates abbotti

The Abbot's gray gibbon, also known as a western gray gibbon, is an acrobatic primate of the gibbons' family, Hylobatidae. Abbott's gray gibbons are very small and light. The Abbott's gray gibbon was named after zoologist William Louis Abbott.

Agile Gibbon

Species Name: Hylobates agilis

Agile gibbons, also known as dark-handed or black-handed gibbons, are arboreal monkeys; they are always in the trees. Agile gibbons belong to the great ape family. However, they are categorized as lesser apes because they are smaller than great apes.

Black-Crested Gibbon

Eastern Black-Crested Gibbon

Species Name: Nomascus nasutus

The eastern black-crested gibbon, also called the Cao-vit crested gibbon or Cao-vit black-crested gibbon, is a gibbon native to northern Vietnam and southeast China. Eastern black-crested gibbons are found in social groups consisting of females, juveniles, infants, and sometimes males.

Eastern Hoolock Gibbon

The eastern hoolock gibbon is a primate of the Hylobatidae family. Eastern hoolock gibbons don't have a tail like all other apes but have a patch of hair in the anogenital region.

Skywalker Hoolock Gibbon

Species Name: Hoolock tianxing

Skywalker's hoolock gibbon, also known as the Gaoligong hoolock gibbon, is a primate of the Hylobatidae family. The Skywalker hoolock gibbon is one of 3 species of hoolock gibbons and was first described in the American Journal of Primatology in January 2017.

Hainan Black-Crested Gibbon

Species Name: Nomascus hainanus

The Hainan black-crested gibbon (Nomascus hainanus), also known as Hainan gibbon, is an endangered species of gibbon only found on China's Hainan Island. Hainan black-crested gibbons are found in social groups of females, infants, juveniles, and sometimes males.

Kloss’s Gibbon

Species Name: Hylobates klossii

Kloss's gibbon (Hylobates klossii), also called the dwarf siamang, Mentawai gibbon, or Bilou, is an endangered primate in the gibbon family Hylobatidae. Kloss's gibbons are territorial, with semi-adult males and adolescents working with their fathers to protect the group's territory.

Silvery Gibbon

Species Name: Hylobates moloch

The silvery gibbon (Hylobates moloch), also called the Javan gibbon, is a primate in the gibbon family, Hylobatidae. Silvery gibbons are tree dwellers and feel just as comfortable in the upper canopy as in the undergrowth.

Northern White-Cheeked Gibbon

Species Name: Nomascus leucogenys

The northern white-cheeked gibbon (Nomascus leucogenys), also called the white-cheeked gibbon, is an endangered species of gibbon endemic to Southeast Asia. Like other members of its genus, both males and females have unusually long arms, even for gibbons, with arms 1.2 to 1.4 times the length of their legs.

Northern Buffed-Cheeked Gibbon

Species Name: Nomascus annamensis

The northern buffed-cheeked gibbon (Nomascus annamensis) is a species of crested gibbon recently discovered in Vietnam, Laos, and Cambodia. Northern buffed-cheeked gibbons live almost exclusively in trees and rarely leave the canopy's comfort and safety.
