Apes (Hominoidea) are

A branch of Old-World tailless simians native to Africa and Southeast Asia. They are distinguished from other primates by a wider degree of freedom of motion at the shoulder joint as evolved by the influence of brachiation. In traditional and non-scientific use, the term "ape" can include tailless primates taxonomically considered monkeys (such as the Barbary ape and black ape), and is thus not equivalent to the scientific taxon Hominoidea. There are two extant branches of the superfamily Hominoidea, the gibbons, or lesser apes, and the hominids, or great apes. Except for gorillas and humans, hominoids are agile climbers of trees. Apes eat a variety of plant and animal foods, with the majority of food being plant foods, which can include fruit, leaves, stalks, roots and seeds, including nuts and grass seeds. All non-human hominoids are rare and endangered. The chief threat to most of the endangered species is loss of tropical rainforest habitat, though some populations are further imperiled by hunting for bushmeat. Ebola infection is currently considered to be the greatest threat to survival of African apes, responsible for the death of at least one third of all gorillas and chimpanzees since 1990.
