Gorillas / Great Apes
Great apes have the largest bodies of all primates. However, there are only five species that fit into this category: orangutans, gorillas, chimpanzees, bonobos — and humans! While humans live all over the globe, orangutans live in the Southeast Asian countries of Borneo and Sumatra, and the rest of the great apes live only in equatorial Africa. Non-human apes live in rainforests and woodlands, and are excellent at climbing, though with the exception of orangutans, they mostly travel on the ground. Unlike the majority of primates, apes do not have tails.
Great apes are well-known for having the most complex social behavior and highest intelligence of all primates. They use facial expressions and complex vocalizations as a part of their social behavior. The great apes have the longest lifespan of all primates, with some living to be 50 years or older.
