Apes are a type of primate that includes gorillas and chimpanzees. Gorillas and chimpanzees are two of the most well-known species of apes, and they share many similarities. Both species have long arms, short legs, and a large head with a prominent brow ridge. They also both have opposable thumbs and walk on their knuckles. Gorillas are typically larger than chimpanzees, and they have longer fur and a more pronounced brow ridge. Chimpanzees, on the other hand, are smaller and have shorter fur and a less pronounced brow ridge. Both species are highly intelligent and social animals, living in groups and communicating with each other through vocalizations and facial expressions.
