The term 'Indian Ape' refers to two species of primates found in India: the GIBBON (Hylobates hoolock) and the langur (Presbytis entellus). The GIBBON is a small, arboreal ape with long arms and legs that it uses to swing from tree to tree. It has a black or brown fur coat and a white face. The langur is a larger primate with a grayish-brown fur coat and a black face. It is an omnivore and lives in troops of up to 30 individuals. Both species are endangered due to habitat loss and poaching. The GIBBON is represented by the 6-letter word 'GIBBON' and the langur is represented by the 3-letter word 'KRA'.
