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]
A proboscis (/ p r oʊ ˈ b ɒ s ɪ s,-k ɪ s /) is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In invertebrates, the term usually refers to tubular mouthparts used for feeding and sucking. In vertebrates, a proboscis is an elongated nose or snout.
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 .
Odd-toed ungulates have a long upper jaw with an extended diastema between the front and cheek teeth, giving them an elongated head. The various forms of snout between families are due to differences in the form of the premaxilla. The lacrimal bone has projecting cusps in the eye sockets and a wide contact with the nasal bone.
(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.
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 ...
The first adaptation is a skull with an elongated snout that may, along with its pointed, recurved and hinged teeth, be an adaptation that assists it to grip its prey. [16] In addition, this elongated snout may also promote binocular vision which would allow strikes to be more accurately directed. [ 9 ]
