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).
They are similar in form and habits to other chimaeras, but have an exceptionally long conical or paddle-shaped snout. [2] The snout has numerous sensory nerve endings, and is used to find food such as small fish. [3] The first dorsal fin includes a mildly venomous spine, used in defense. [4]
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 .
Rhinochimaera pacifica grows to a total length of roughly 130 cm, with a body length of roughly 62 cm. Female specimens are typically larger than males. [1] It has a long, narrow snout and smooth tooth plates. The snout is elongated, and its length can be anywhere from 50 to 87% of the body length, ending at a blunted tip. [3]
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.
They have a “cylindrical” body, “long” tail and “wedge-shaped snout.” On their eyelids, the skinks have a “transparent,” window-like scale. A photo shows the speckled coloring of a ...
The critter’s robust skull had additional bones and elements that have likely disappeared with evolution, and its elongated snout paired with a short region of the skull behind the eyes was ...
(A) through (D) possess a rhinarium and are strepsirrhines, whereas (E) does not and is a haplorhine. Strepsirrhines have a long snout that ends in a moist and touch-sensitive rhinarium, similar to that of dogs and many other mammals. The rhinarium is surrounded by vibrissae that are also sensitive to touch.
