The term CHIMP RELATIVES refers to the two species of great apes that are closely related to chimpanzees: orangutans and gorillas. Orangutans, which have six letters, are native to Indonesia and Malaysia and are the largest arboreal animals in the world. They are known for their reddish-brown fur and long arms. Gorillas, on the other hand, are native to Africa and are the largest living primates. They are characterized by their black fur and large size.
