Physical characteristics of great apes:
* Size: Great apes are the largest primates. Adult males typically weigh between 100 and 250 pounds, while adult females weigh between 70 and 150 pounds.
* Arms: Great apes have long arms that are longer than their legs. This allows them to swing through trees and climb easily.
* Legs: Great apes have short legs that are used for walking and standing.
* Tail: Great apes lack a tail.
* Brain: Great apes have a relatively large brain. The human brain is the largest, followed by the gorilla, chimpanzee, and orangutan brains.
* Social behavior: Great apes are capable of complex social behavior. They live in groups and have a variety of social interactions, such as grooming, playing, and hunting.
Great apes are an endangered species. Their populations are declining due to habitat loss, poaching, and the pet trade. It is important to protect these animals and their habitat so that they can continue to thrive.
