Atrophacanthus Japonicus
''Atrophacanthus'' is a monospecific genus of marine ray-finned fish belonging to the family Triacanthodidae, the spikefishes. The only species in the genus is ''Atrophacanthus japonicus'', the upward-mouth spikefish, which is found in the Indo-West Pacific region. Taxonomy ''Atrophacanthus'' was first proposed as a monospecific genus in 1950 by the British ichthyologist Alec Fraser-Brunner when he described ''Atrophacanthus danae'', its type species by monotypy. Fraser-Brenner's ''A. danae'' had its type locality given as the Sulawesi Sea. ''A. danae'' was subsequently shown to be a synonym of ''Tydemania japonica'' which had been described in 1941 by the Japanese ichthyologist Toshiji Kamohara with its type locality given as Shikoku in the Kōchi Prefecture, Japan. This taxon is classified within the subfamily Triacanthodinae of the spikefish family Triacanthodidae, within the suborder Triacanthoidei of the order Tetraodontiformes in the 5th edition of ''Fishes of the World ...

Alec Frederick Fraser-Brunner
Alec Frederick Fraser-Brunner (6 April 1906 – 17 Sept 1986) was a British ichthyologist. His career included work with the Colonial Office, the Food and Agriculture Organization, and as the curator of the Van Kleef Aquarium in Singapore and the aquarium at Edinburgh Zoo. Amongst his written works is ''Cussons Book of Tropical Fishes'', published as result of Manchester industrialist Alexander Tom Cussons' interest in tropical fish. Cussons had a keen interest in orchids. The hot-houses in which he grew them proved to be well-suited to tropical fish aquariums. Alec Frederick Fraser-Brunner is the designer of Singapore's iconic national symbol, the Merlion. The Merlion was originally designed for the Singapore Tourism Board The Singapore Tourism Board (STB) is a statutory board under the Ministry of Trade and Industry of the Government of Singapore, tasked to promote the country's tourism industry. History The board was first established on 1 January 1964 and ... as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kōchi Prefecture
is a prefecture of Japan located on the island of Shikoku. Kōchi Prefecture has a population of 669,516 (1 April 2023) and has a geographic area of 7,103 km2 (2,742 sq mi). Kōchi Prefecture borders Ehime Prefecture to the northwest and Tokushima Prefecture to the northeast. Kōchi is the capital and largest city of Kōchi Prefecture, with other major cities including Nankoku, Shimanto, and Kōnan. Kōchi Prefecture is located on Japan's Pacific coast surrounding a large bay in the south of Shikoku, with the southernmost point of the island located at Cape Ashizuri in Tosashimizu. Kōchi Prefecture is home to Kōchi Castle, considered the most intact Japanese castle, and the Shimanto River, one of the few undammed rivers in Japan. History Antiquity Before the Ritsuryō System In the Kujiki, first recorded governments in Kōchi Prefecture were Hata (in the west) and Tosa (in the center). Hata was established first, so it is thought that it had more influen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pectoral Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish aquatic locomotion, swim. Apart from the tail or caudal fin, fish fins have no direct connection with the vertebral column, back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bone, bony spine (zoology), spines or ray (fish fin anatomy), rays covered by a thin stretch of fish scale, scaleless skin; in lobe-finned fish (Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central limb bud, bud supported by appendicular skeleton, jointed bones; in cartilaginous fish (Chondrichthyes) and jawless fish (Agnatha), fins are fleshy "flipper (anatomy), flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most 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 whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Macrorhamphosodes
''Macrorhamphosodes'', the trumpetsnouts, is a genus of marine ray-finned fishes belonging to the family Triacanthodidae, the spikefishes. The fishes in this genus are found in the deep waters of the Indian and Pacific Oceans. Taxonomy ''Macrorhamphosodes'' was first proposed as a monospecific genus in 1934 by the American zoologist Henry Weed Fowler with ''Macrorhamphosodes platycheilus'' designated as its type species, and its only species. ''M. platycheilus'' was also described by Fowler in 1934 and its type locality given as Sombrero Island off Luzonin the Philippines from Albatross station 5118 from a depth of . In 1933 the Japanese ichthyologist Toshiji Kamohara has described ''Halimochirus uradoi'' from Kochi Prefecture in Japan, the genus name was a misspelling of ''Halimochirurgus''. In 1968 James C. Tyler reclassified this species to this genus as ''M. uradoi''. Also in 1968, Tyler classified this genus in the nominate subfamily of the family Triacanthodidae, the Tri ...
