Rostrum (from Latin rostrum, meaning beak) is a term used in anatomy for several kinds of hard, beak-like structures projecting out from the head or mouth of an animal. Despite some visual similarity, many of these are phylogenetically unrelated structures in widely varying species.
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 .
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 eyes, set high on the head, are often green in color. The snout is used to probe the sea bottom in search of the invertebrates and small fishes [inconsistent] on which it preys. [1] The remainder of the body is flat and compressed, often described as elongated. The mouth is just under this snout and the eyes are located high on top of the head.
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 ...
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.
The new species was identified by its snout, scale pattern, coloring and other physical features, the study said. DNA analysis found the new species had at least about 1% genetic divergence from ...
