What is the difference between monkey ape gorilla chimpanzee orangotan lemur ?

Lemurs are Prosimians, while the rest of the animals in your list are Simians. You can think of them as a lesser monkey. They don't have the color or the binocular vision usually associated with monkeys and have a wet nose like a dog. They are only found naturally on Madagascar.





Gorilla's, Chimpanzees and Orangatans are all Apes and along with Humans, Gibbons and Bonobo's are the only ape species. They differ from monkeys in that they don't have a tail, have modified shoulder's, specific dental adaptations, specific spinal adaptations, and specific eye adaptations.
