A snout is the protruding portion of an animal's face, consisting of its nose, mouth, and jaw. In many animals, the structure is called a muzzle , [ 1 ] rostrum , beak or proboscis . The wet furless surface around the nostrils of the nose of many mammals is called the rhinarium (colloquially this is the "cold wet snout" of some mammals).
The rhinarium (Neo-Latin, "belonging to the nose"; pl.: rhinaria) [1] is the furless skin surface surrounding the external openings of the nostrils in many mammals.Commonly it is referred to as the tip of the snout, and breeders of cats and dogs sometimes use the term nose leather.
Their form in living species is highly variable, depending on the shape of the head, but they generally form the roof of the snout or beak, running from the nostrils to a position short of the orbits. In most animals, they are generally therefore proportionally larger than in humans or great apes, because of the shortened faces of the latter.
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
The beak or snout of a vertebrate may also be referred to as the rostrum. Some cetaceans, including toothed whales such as dolphins [7] [8] and beaked whales, have rostrums (beaks) which evolved from their jawbones. The narwhal possesses a large rostrum (tusk) which evolved from a protruding canine tooth.
The elephant's trunk and the tapir's elongated nose are called "proboscis", as is the snout of the male elephant seal. Notable mammals with some form of proboscis are: Aardvark; Anteater; Elephant; Elephant shrew; Hispaniolan solenodon; Echidna; Elephant seal; Leptictidium (extinct) Moeritherium (extinct) Numbat; Proboscis monkey; Saiga ...

[1] An aquiline nose (also called a Roman nose) is a human nose with a prominent bridge, giving it the appearance of being curved or slightly ...
The snout of adult gharials is 3.5 times longer than the width of the skull's base. [36] Because of this long snout the gharial is especially adapted to catching and eating fish. [4] The nasal bones are rather short and widely spaced from the premaxillae. The jugal bone is raised. [36] It becomes proportionally thicker with age. [39]
