edThe difference between a monkey and a chimpanzee lies mainly in their physical characteristics. Chimpanzees, which are part of the Great Ape family, are larger than monkeys, with a height of up to 4-5 feet and an average weight of 100-120 pounds. Monkeys, on the other hand, are much smaller, reaching heights of up to 2-3 feet, and have a much lighter average weight of 30-75 pounds.
Chimpanzees also have rounder and flatter faces than monkeys, and their mouths are much less protruding. Additionally, chimpanzees possess the unique feature of an opposable thumb and their bodies are covered in long hair, whereas monkeys often have short or no fur.
Furthermore, chimpanzees also possess larger brains than monkeys, making them more intelligent and able to use tools, whereas monkeys typically do not.
