Examples include the common wombat, marsupial mole, and members of the Chrysochloridae. In elephants, the rhinarium has become a tactile organ. And in the walrus, a covering of stiff bristles protects it while the animal forages for shellfish. In many animals, the form and purpose of the rhinarium remains unclear.
The rhinarium is a greatly enlarged, dry leathery pad that protects their nostrils while the animal digs. In this respect, too, they resemble the marsupial moles. In this respect, too, they resemble the marsupial moles.
Haplorhini (/ h æ p l ə ˈ r aɪ n aɪ /), the haplorhines (Greek for "simple-nosed") or the "dry-nosed" primates is a suborder of primates containing the tarsiers and the simians (Simiiformes or anthropoids), as sister of the Strepsirrhini ("moist-nosed").
Leopardus species have spotted fur, with ground colors ranging from pale buff, ochre, fulvous and tawny to light gray. [5] Their small ears are rounded and white-spotted; their rhinarium is prominent and naked above, and their nostrils are widely separated. [6]
The African sheath-tailed bat weighs 10–12 grams (0.35–0.42 oz), with females slightly larger than males. Forearm lengths range from 45 to 55 millimetres (1.8 to 2.2 in). The fur is a deep brown, but slightly lighter on the belly. The nose is a pointed cone shape and the rhinarium is black and naked. [2]
Tarsiers (/ ˈ t ɑːr s i ər z / TAR-see-ərz) are haplorhine primates of the family Tarsiidae, which is, itself, the lone extant family within the infraorder Tarsiiformes.Although the group was, prehistorically, more globally widespread, all of the species living today are restricted to Maritime Southeast Asia, predominantly in Brunei, Indonesia, Malaysia and the Philippines.
The family accords with the description to the type genus Rhinonicteris, and its classification of the morphology of the rhinarium.The revision of Hill in 1982 follows Gray to describe the features of the nose-leaf for the subfamilial group, and these provide diagnosis to distinguish the species from other families.
In most mammals, the philtrum is a narrow groove that may carry dissolved odorants from the rhinarium or nose pad to the vomeronasal organ via ducts inside the mouth. [4] For humans and most primates, the philtrum survives only as a vestigial medial depression between the nose and upper lip. [5]
