Paracaristius
''Paracaristius'' is a genus of ray-finned fish in the family Caristiidae, the manefishes. It is a small genus with mostly newly described species.Stevenson, D. E. and C. P. Kenaley. (2011)Revision of the manefish genus ''Paracaristius'' (Teleostei: Percomorpha: Caristiidae), with descriptions of a new genus and three new species.''Copeia'' 2011(3) 385-99. Fish in this genus are separated from similar taxa by the arrangement of their teeth. They have compressed heads with very short snouts, small mouths, and two nostrils. The body is oval to rectangular.

Neocaristius Heemstrai
''Neocaristius heemstrai'' is a species of fish in the family Caristiidae, the manefishes. It is native to the oceans of the southern hemisphere where it is known to occur at depths of from . This species grows to a length of SL. This fish was first described in 2006 and was moved to a monotypic genus In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispe ... of its own, ''Neocaristius'', in 2011. Etymology The fish is named in honor of Phillip C. Heemstra (1941-2019), of the J.L.B. Smith Institute of Ichthyology in Grahamstown, South Africa, for his contributions to the studies of marine fishes, and in 1986 was the first to draw attention to this species.

Caristiidae
Caristiidae, the manefishes, are a family of scombriform ray-finned fishes which today includes 19 extant taxon, extant species distributed in four genera. Taxonomy The following genera are known: * ''Caristius'' Theodore Nicholas Gill, Gill & Hugh McCormick Smith, Smith, 1905 * ''Neocaristius'' Stevenson & Kenaley, 2011 * ''Paracaristius'' Ivan Andreevich Trunov, Trunov, Yefim Izrailevich Kukuev, Kukuev & Nikolai Vasilyevich Parin, Parin, 2006 * ''Platyberyx'' Erich Zugmayer, Zugmayer, 1911 In addition, the extinct genera ''Chalcidichthys malacapterygius, Chalcidichthys'' and ''Absalomichthys'' are known from the Late Miocene of Southern California. Biology They are deep-sea marine fishes found in the mesopelagic zone that eat siphonophores. An adult manefish is less than 25 cm in length and most of them are entirely black, which helps camouflage them from predators. References Caristiidae, Percomorpha families {{Scombroidei-stub ...

Ivan Andreevich Trunov
Ivan () is a Slavic male given name, connected with the variant of the Greek name (English: John) from Hebrew meaning 'God is gracious'. It is associated worldwide with Slavic countries. The earliest person known to bear the name was the Bulgarian Saint Ivan of Rila. It is very popular in Russia, Ukraine, Croatia, Serbia, Bosnia and Herzegovina, Slovenia, Bulgaria, Belarus, North Macedonia, and Montenegro and has also become more popular in Romance-speaking countries since the 20th century. Etymology Ivan is the common Slavic Latin spelling, while Cyrillic spelling is two-fold: in Bulgarian, Russian, Macedonian, Serbian and Montenegrin it is , while in Belarusian and Ukrainian it is . The Old Church Slavonic (or Old Cyrillic) spelling is . It is the Slavic relative of the Latin name , corresponding to English ''John''. This Slavic version of the name originates from New Testament Greek (''Iōánnēs'') rather than from the Latin . The Greek name is in turn derived fro ...

Nikolai Vasilyevich Parin
Nikolai Vasilyevich Parin (21 November 1932 – 18 April 2012) was a Soviet and Russian ichthyologist, specializing in oceanic pelagic fish. He headed the Laboratory of Oceanic Ichthyofauna at the RAS Institute of Oceanology in Moscow, where he ended his career as a Professor after more than fifty-seven years. In his career, he described more than 150 new taxa of fish and participated in 20 major oceanic expeditions. Thirty-six species of fish are named in his honour. Personal life Parin was born in Perm on 21 November 1932. His father was Vasily Vasilevich Parin, who was the founder and first Secretary General of the USSR Academy of Medicine but later was made politically suspect due to a trip to the United States and a dispute with Trofim Lysenko. After the death of Stalin in 1953 and rise of Khrushchev, his father was rehabilitated and played a key medical role in the Soviet space program. Because of his father's imprisonment, Parin could not study physics at Moscow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

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 ...

Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines play an important role in schooling behavior, predation, and orientation. Early in the evolution of fish, some of the sensory organs of the lateral line were modified to function as the electroreceptors called ampullae of Lorenzini. The lateral line system is ancient and basal to the vertebrate clade, as it is found in fishes that diverged over 400 million years ago. Function The lateral line system allows the detection of movement, vibration, and pressure gradients in the water surrounding an animal. It plays an essential role in orientation, predation, and fish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
