Great Apes

 Apes (Hominoidea) are a branch of Old World tailless simians which are found within the tropical forests of western and Central Africa and Southeast Asia . Apes are distinguished from monkeys by the entire absence of a tail and therefore the presence of an appendix and by their more complex brains. The gorilla, chimpanzee, bonobo, and orangutan are called great apes in recognition of their comparatively large size and humanlike features; the gibbons are called lesser apes. the great apes are far more intelligent than monkeys and gibbons. The lesser apes are the gibbon family, Hylobatidae, of sixteen species; which are native to Asia. The major differentiating characteristic of lesser apes is their long arms, which they use to brachiate through trees. The Hominoidea falls within the parvorder Catarrhini, which also includes the Old World monkeys of Africa and Eurasia. Within this grouping, the 2 families Hylobatidae and Hominidae are often distinguished from Old World monkeys by the number of cusps on their molars; hominoids have five within the "Y-5" molar pattern, whereas Old World monkeys have only four during a bilophodont pattern. excluding humans and gorillas, apes eat a predominantly frugivorous diet, mostly fruit, but supplemented with a range of other foods. Gorillas are predominately folivorous, eating mostly stalks, shoots, roots and leaves with some fruit and other foods. Non-human apes usually eat alittle amount of raw animal foods like insects or eggs.
