Main Difference – Monkey vs Ape
Monkey and ape are two members of the order Primates. Both types of animals share significantly common features as well as differences. The facial features such as forward-facing eyes, dexterous fingers, and highly flexible limbs including arms and legs are the common features seen in both monkeys and apes. Moreover, the body of both monkey and ape is covered with a short, dense hair. The main difference between monkey and ape is that monkeys have a tail whereas apes do not have a tail. The size of the brain, mental capabilities, and the lifespan of monkey and ape may also possess significant differences.

Monkey – Physical and Mental Characteristics
Monkey refers to a small primate with a long tail, living in trees of the tropical countries. The two categories of monkey are old-world monkey and new-world monkey. Old-world monkey belongs to the superfamily Cercopithecoidea, and new-world monkey belongs to the superfamily Platyrrhini.
Old-world monkeys live in Asia and Africa. They are larger than new-world monkeys. The nostrils of the old-world monkeys are narrow and point downward. The hind legs are longer than the forearms. They have flattened nails on both fingers and toes. They also consist of prominent buttock pads on which they sit. Cercopithecinae (cheek-pouched monkeys) and Colobinae (leaf-eating monkeys) are the two subfamilies of old-world monkeys. An old-world monkey is shown in figure 1.
New-world monkey live in neotropical forests in Central and South America. The size of these monkeys may vary from 6 inches (pygmy marmoset) to 3 feet (howler monkey) in length. The nostrils of new-world monkey are wide and circular. They are spaced apart as well. These monkeys have long tails, which sometimes serve as a prehensile. They lack buttock pads and cheek pouches. A new-world monkey is shown in figure 2.
Callitrichidae and Cebidae are the two families of new-world monkeys. Marmosets and smaller tamarins belong to Callitrichidae and capuchin, titi, spider, wooly, owl, and saki monkeys belong to Cebidae.
Ape – Mental and Physical Characteristics
Ape refers to a large primate that does not have a tail. The apes belong to the superfamily Catarrhini. The two categories of apes are great apes and lesser apes. The great apes belong to the family Hominidae while lesser apes belong to the family Hylobatidae.
Gorillas, chimpanzees, orangutans, bonobos, and humans are great apes. The face of great apes is not covered with hair. The ears are round, and they do not have cheek pouches. The fingers are opposable, and the thumb is shorter. The great apes are bipedal. They rely on vision rather than smell. They also have a wide range of facial expressions and vocalizations. They are intelligent and are capable of thinking as well. An orangutan is shown in figure 3.
Lesser apes consist of gibbons. They are smaller than great apes and live in pairs. The largest type of lesser apes are siamangs. A male siamang is shown in figure 4.
The most dangerous type of apes is humans. He destroys the habitats of other apes and hunts other apes for bushmeat.
