Laubuka Latens
''Laubuka latens'' is a species of small fish of the minnow and carp family, Cyprinidae, and the Danio subfamily. It was described in 2015 from specimens collected in the Cauvery River and its tributaries in the Western Ghats of India. This species and '' Laubuka trevori'' had been thought to be local variants of the Indian glass barb (''L. laubuca'') but were shown to be different species. The unique features of ''L. latens'' are that it has 7½ branched rays in its dorsal fin with 5 branched rays in its pelvic fin; it has 14 precaudal vertebrae and 17–18 predorsal scales; aw s well as 5+4+2 teeth on the fifth ceratobranchial Branchial arches, or gill arches, are a series of bony "loops" present in fish, which support the gills.

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Cauvery River
The Kaveri (also known as Cauvery, the anglicized name) is one of the major Indian rivers flowing through the states of Karnataka and Tamil Nadu. The Kaveri river rises at Talakaveri in the Brahmagiri range in the Western Ghats, Kodagu district of the state of Karnataka, at an elevation of 1,341 m above mean sea level and flows for about 800 km before its outfall into the Bay of Bengal. It reaches the sea in Poompuhar in Mayiladuthurai district. It is the third largest river after Godavari and Krishna in southern India, and the largest in the State of Tamil Nadu, which, on its course, bisects the state into north and south. In ancient Tamil literature, the river was also called Ponni (the golden maid, in reference to the fine silt it deposits). The Kaveri is a sacred river to the people of South India and is worshipped as the Goddess Kaveriamma (Mother Cauvery). It is considered to be among the seven holy rivers of India. It is extensively used for agriculture in bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laubuka Trevori
''Laubuka trevori'' is a species of small fish of the minnow and carp family, Cyprinidae, and the Danio subfamily. It was described in 2015 from specimens collected in the Cauvery River and its tributaries in the Western Ghats of India. This species and '' Laubuka latens'' had been thought to be local variants of the Indian glass barb (''L. laubuca'') but were shown to be different species. The unique features of ''L. latens'' are that it has 7½ branched rays in its dorsal fin with 5 branched rays in its pelvic fin; it has 14 precaudal vertebrae and 17–18 predorsal scales; aw s well as 5+4+2 teeth on the fifth ceratobranchial bone. ''L. trevori'' has 14½–15½ branched rays in its anal fin, a relatively short pelvic fin which is about a fifth as long as its standard length Fish measurement is the measuring of individual fish and various parts of their anatomies.

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelvic Fin
Pelvic fins or ventral fins are paired fins located on the ventral surface of fish. The paired pelvic fins are homologous to the hindlimbs of tetrapods. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays (lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into a spiny copulatory device that grasps the female during mating.

Vertebrae
The spinal column, a defining synapomorphy shared by nearly all vertebrates,Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage. They show variation in the proportion contributed by these two tissue types; such variations correlate on one hand with the cerebral/caudal rank (i.e., location within the vertebral column, backbone), and on the other with phylogenetic differences among the vertebrate taxon, taxa. The basic configuration of a vertebra varies, but the bone is its ''body'', with the central part of the body constituting the ''centrum''. The upper (closer to) and lower (further from), respectively, the cranium and its central nervous system surfaces of the vertebra body support attachment to the intervertebral discs. The posterior part of a vertebra fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Branchial Arch
Branchial arches, or gill arches, are a series of bony "loops" present in fish, which support the gills. As gills are the primitive condition of vertebrates, all vertebrate embryos develop pharyngeal arches, though the eventual fate of these arches varies between taxa. In jawed fish, the first arch develops into the jaws, the second into the hyomandibular complex, with the posterior arches supporting gills. In amphibians and reptiles, many elements are lost including the gill arches, resulting in only the oral jaws and a hyoid apparatus remaining. In mammals and birds, the hyoid is still more simplified. All basal vertebrates breathe with gills. The gills are carried right behind the head, bordering the posterior margins of a series of openings from the esophagus to the exterior. Each gill is supported by a cartilaginous or bony gill arch. Bony fish have four pairs of arches, cartilaginous fish have five to seven pairs, and primitive jawless fish have seven. The vertebrate ...
