Stephanoberyciformes
The Stephanoberycoidei is a suborder of marine ray-finned fishes, consisting of about 68 species, the majority (61) of which belong to the ridgehead family (biology), family (Melamphaidae). They were formerly placed as their own order, the Stephanoberyciformes. However, more recent taxonomic sources treat them as a suborder of the Beryciformes. The Stephanoberyciformes are mostly uncommon deep sea fish, deep-sea species with little, if any, importance to commercial fishery. They share many morphological similarities with the Berycoidei, their sister order. They are usually found in Australian waters. The whalefishes, which were formerly treated as their own order, are now also placed in this group. Some families treat them as a Taxonomic rank, superfamily within the group named Cetomimoidea; most taxa traditionally placed here would then be the Stephanoberycoidea. The family (biology), families are: * Family Stephanoberycidae Theodore Gill, Gill, 1884 (pricklefishes) * Family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velvet Whalefish
The velvet whalefish (''Barbourisia rufa'') is a deep-sea whalefish, the sole known member of its family Barbourisiidae. It is found throughout the tropical and temperate parts of the world's oceans, mainly in the Pacific near Japan and New Zealand, at depths of 300–2,000 m. This species seems very closely related to some flabby whalefish and it was initially believed to belong to that family by some. They have been found from 65°N–40°S in the Atlantic, 50°N–50°S in the Pacific, and 5–20°S in the Indian Ocean. Like other whalefish, it has a generally whale-shaped body, small pectoral and pelvic fins, and dorsal and anal fins set far back. Body and fins are covered with tiny wikt:spicule, spicules, resulting in a velvety feel that inspires the name. Colour is an overall vivid geranium red or dark orange. The mouth is large, extending well behind the eyes, has a white interior, and the lower jaw projects beyond the upper jaw. The largest recorded specimen was 34.5& ...

Whalefish
The Cetomimoidea or whalefishes are a superfamily of small, deep-sea ray-finned fish. Formerly treated as either their own order (Cetomimiformes) due to their unusual anatomy, more recent studies incorporating genetic data confirm them to be deeply nested within the Beryciformes as a clade within Stephanoberycoidei (which was formerly also treated as its own order). They are thus better treated as their own superfamily, Cetomimoidea. Within this group are five families and approximately 18 genera and 32 species (but see below). Thought to have a circumglobal distribution throughout the tropical and temperate latitudes, whalefishes have been recorded at depths in excess of 3,500 metres. Taxonomy Some recent phylogenetic studies suggest that the whalefishes are paraphyletic with respect to other members of the suborder, with '' Barbourisia'' belonging to the Stephanoberycidae while Rondeletiidae includes '' Hispidoberyx''. Although previously thought to have ancient origins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scopelogadus Mizolepis
''Scopelogadus'' is a genus of ridgeheads. The generic name derives from the Greek σκόπελος (''skopelos'', "lanternfish Lanternfish (or myctophids, from the Greek language, Greek μυκτήρ ''myktḗr'', "nose" and ''ophis'', "serpent") are small mesopelagic fish of the large family (biology), family Myctophidae.

Species There are currently three recognized species in this genus: * '' Scopelogadus beanii'' ( Günther, 1887) (Bean's bigscale) * '' Scopelogadus mizolepis'' (Günther, 1878) ** '' Scopelogadus mizolepis bispinosus'' ( C.

Redmouth Whalefish
The redmouth whalefishes are two species of deep-sea whalefishes in the genus ''Rondeletia'', the only genus in the family Rondeletiidae. They are apparently close to the velvet whalefish (''Barbourisia rufa''), and apparently also to the gibberfishes (Gibberichthyidae). The latter and the Rondeletiidae are the only known living fishes which have the mysterious Tominaga's organ. Like the plant genus of the same name, this genus is named after Guillaume Rondelet. Redmouth whalefishes are small fishes. ''Rondeletia bicolor'' grows to about 6 cm long or so. It is most commonly found in the northern Atlantic, but has been documented from the eastern Pacific, as well, and presumably also occurs in the rest of the Atlantic. The better-known ''Rondeletia loricata'' is known from all oceans between 47°N–47°S; it has been recorded to reach a length of more than 9 cm when adult. Usually found in deep waters of tropical and temperate oceans around the world, down to 3,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Palate
The palate () is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. A similar structure is found in crocodilians, but in most other tetrapods, the oral and nasal cavities are not truly separated. The palate is divided into two parts, the anterior, bony hard palate and the posterior, fleshy soft palate (or velum). Structure Innervation The maxillary nerve branch of the trigeminal nerve supplies sensory innervation to the palate. Development The hard palate forms before birth. Variation If the fusion is incomplete, a cleft palate results. Function in humans When functioning in conjunction with other parts of the mouth, the palate produces certain sounds, particularly velar, palatal, palatalized, postalveolar, alveolopalatal, and uvular consonants. History Etymology The English synonyms palate and palatum, and also the related adjective palatine (as in palatine bone), are all from the Latin ''palatum' ...

Tarleton Hoffman Bean
Tarleton Hoffman Bean (October 8, 1846 – December 28, 1916) was an American ichthyologist. Biography and education Tarleton Hoffman Bean was born to George Bean and Mary Smith Bean in Bainbridge, Pennsylvania, on October 8, 1846. He attended State Normal School at nearby Millersport, Pennsylvania, graduating in 1866. He received an M.D. degree from Columbian University, now George Washington University, Washington, DC, 1876. In 1883, he was awarded an M.S. degree from the Indiana University on the basis of his professional accomplishments, although he did not attend classes there. He married Laurette H. van Hook, daughter of John Welsh VanHook, a local Washington businessman, in 1878 in Washington, DC. They had one daughter, Caroline van Hook Bean (born in Washington on November 16, 1879), a noted artist who later married Bernardus Blommers, Jr. His brother, Barton Appler Bean, also became an ichthyologist and worked under him at the National Museum.
