Mouth wiki:
>For the mouth of a river, see delta and estuary. The mouth, also known as the buccal cavity or the oral cavity, is the opening through which an animal or human takes in food. It is usually located in the head, but not always; the mouth of a planarium is in the middle of its belly.Most animals have a complete digestive system, with a mouth at one end and an anus at the other. Which end forms first in ontogeny is a criterion used to classify animals into protostome and deuterostome.Some animals, such as the cnidarians and the planaria, have no anus. They expel waste through the mouth, or as do brachiopods, which have very efficient digestive systems, roll it around in the stomach until it is finished.

orangutan wiki:
>For the chess opening, see Sokolsky Opening. Pongo pygmaeus Pongo abelii Orangutans (also spelled orang utan, orang-utan, sometimes incorrectly orangutang) are two species of great apes with long arms and reddish, sometimes brown, hair native to Malaysia and Indonesia. The word orangutan is derived from the Malay orang hutan meaning man of the forest, although local people do not use this term to refer to orangutans. The Malay word for orangutan is maias or mawas. They are the only extant species in the genus Pongo and the subfamily Ponginae, although that subfamily also includes the extinct Gigantopithecus and Sivapithecus genera. Orang Utan is a official state animal of Sabah in Malaysia.
