3. Gorilla Classification – Gorilla Taxonomy

Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Primates
Suborder: Haplorhini

4. Gorilla Family

  • Gorilla belongs to Hominidae family.
  • It is a family of primates whose members are called hominids or great apes.
  • This family include four genera that contain eight existent species.
  • One of these genera is the genus Gorilla, which includes the Western Gorilla and Eastern Gorilla.
  • Genus Pongo includes the Sumatran, Tapanuli and Bornean Orangutans.
  • Genus Pan includes the Bonobo and the common Chimpanzees.
  • And genus Homo includes the modern Humans (Homo sapiens), their extinct relatives (such as the Neanderthals) and their ancestors (for example the Homo erectus).

5. Gorilla Name

  • The origin of the word “Gorilla” is the history of a Carthaginian explorer, Hanno the Navigator (approximately 500 BC), who was on an expedition on the coast of west Africa to the region that is now Sierra Leone.
  • There, he and his fellows unexpectedly met savage people, a larger part of whom were women with hairy bodies, whom were called by their translators as “Gorillae”.
  • Later, the word “Gorilla” was used as a name of species, however, it is unknown whether these ancient Carthaginian expediters encountered actual gorillas or another species of monkeys, apes, or humans.

6. What is a Female Gorilla Called – Female Gorilla Name

  • Female gorillas do not have any special gender based name.
  • However, adult male gorillas are called “Silverbacks” because of the growth of silver hair on their backs and hips after the age of 12 years.
  • The sexually mature younger male gorillas of ages between 8 to 12 years are called  “Blackbacks” due to the lack of silver hair on their backs.
  • The Blackbacks are lower in position than the Silverbacks.
