Rhinopias Aphanes
''Rhinopias aphanes'', the lacy scorpionfish, weedy scorpionfish or Merlet's scorpionfish, is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. This species is found in the Western Pacific. It occasionally makes its way into the aquarium trade. Taxonomy ''Rhinopias aphanes'' was first formally described in 1973 by the American ichthyologist William N. Eschmeyer with the type locality given as New Caledonia. The specific name ''aphanes'' means "that which is unseen or inconspicuous", an allusion to the camouflage created by its notable coloration and flaps of skin. Description ''Rhinopias aphanes'' has two black spots in the middle of the membrane between the sixth and eighth rays of the dorsal fin, while '' R. argoliba'', '' R. cea'' and '' R. xenops'' all lack them. Therefore, this feature allows us to distinguish this species from its relatives; other differences include the lack of scales on the operculum between the tips of t ...

William N
William is a male given name of Germanic origin.Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford University Press, 2nd edition, , p. 276. It became very popular in the English language after the Norman conquest of England in 1066,All Things William"Meaning & Origin of the Name"/ref> and remained so throughout the Middle Ages and into the modern era. It is sometimes abbreviated "Wm." Shortened familiar versions in English include Will, Wills, Willy, Willie, Bill, and Billy. A common Irish form is Liam. Scottish diminutives include Wull, Willie or Wullie (as in Oor Wullie or the play ''Douglas''). Female forms are Willa, Willemina, Wilma and Wilhelmina. Etymology William is related to the given name ''Wilhelm'' (cf. Proto-Germanic ᚹᛁᛚᛃᚨᚺᛖᛚᛗᚨᛉ, ''*Wiljahelmaz'' > German ''Wilhelm'' and Old Norse ᚢᛁᛚᛋᛅᚼᛅᛚᛘᛅᛋ, ''Vilhjálmr'').

Rhinopias Xenops
''Rhinopias xenops'', the strange-eyed scorpionfish, is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. This species is found in the Pacific Ocean. Taxonomy ''Rhinopias xenops'' was first formally described as ''Peloropsis xenops'' in 1905 by the American ichthyologist Charles Henry Gilbert with the type locality given as the Avau Channel, the channel separating the islands of Maui and Lanai in Hawaii. ''Peloropsis'' was also a new genus and ''P. xenops'' was its only species. However, in 1973 William N. Eschmeyer, Yoshitsugu Hirosake and Tokiharu Abe moved this species into the genus ''Rhinopias'', making ''Peloropsis'' a junior synonym of that taxon. The specific name ''xenops'' is a compound of ''xeno'' meaning “different” and ''ops'' meaning “eye”, an allusion to the raised upper orbits of the eyes sticking above the dorsal profile of the head. Description ''Rhinopias xenops'' has 12 spines and 9 soft rays in the dor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinopias
''Rhinopias'' is a genus of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. The species in this genus are found in the Indian and Pacific oceans. Taxonomy ''Rhinopias''was described as a genus in 1905 by the American ichthyologist Theodore Gill, Gill described it as a monotypic genus and designated ''Scorpaena frondosa'' as its type species. ''Scorpaena frondosa'' had originally been described in 1893 by the German-born British zoologist Albert Günther with its type locality given as Mauritius. The genus name is a combination of ''rhino'' meaning "snout" and ''op'' meaning "eye", an allusion to he upturned snout and raised orbits of ''R. frondosa'' with the suffix ''ias'' which is used in some Greek names for fishes, for example ''Xiphias''. Species There are six recognized species in this genus There is some doubt as to whether ''R. eschmeyeri'' is a synonym of ''R. frondosa'', with the two possibly being different sexes of a sexually dimor ...

List Of Marine Aquarium Fish Species
The following list of marine aquarium fish species commonly available in the aquarium trade is not a completely comprehensive list; certain rare specimens may be available commercially but not yet listed here. A brief section on each, with a link to the page about the particular species is provided along with references for further information. Angelfish (large) These large fish are considered to be quite hardy, but because of their size may present a significant challenge to the keeper. They need huge aquariums, up to 180 gallons to house one for its entire lifespan. Two angels might be kept in the same aquarium provided it is a large aquarium, they are properly acclimated as juveniles, and they have very different colouring and body shape. However, because all Angelfish have essentially the same diet, mixing them is a feat that should be left to only advanced keepers. Most are not reef safe, and a potential owner should be aware that they need to have plenty of vegetab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 serve an important role in schooling behavior, predation, and orientation. Fish can use their lateral line system to follow the vortices produced by fleeing prey. Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. In some species, the receptive organs of the lateral line have been modified to function as electroreceptors, which are organs used to detect electrical impulses, and as such, these systems remain closely linked.

Rhinopias Frondosa
''Rhinopias frondosa'', the weedy scorpionfish or the weed fish, is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. This species is found in the Indo-West Pacific. It is a rare but highly desirable fish in the aquarium trade. Taxonomy ''Rhinopias frondosa'' was first formally described in 1892 by the German-born British zoologist Albert Günther with the type locality given as Mauritius. When Theodore Gill described the new monotypic genus ''Rhinopias'' in 1905 he designated this species as its type species. This species has been seen associating with '' R. eschmeyeri'' in pairs and it has been suggested that these are the different sexes in a sexually dimorphic single species. The specific name ''frondosa'' means "branched or full of leaves", an allusion to the fleshy tentacles which cover most of the body of this fish. Description ''Rhinopias frondosa'' has a highly compressed body which is covered in weed like tentacles. It h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinopias Eschmeyeri
''Rhinopias eschmeyeri'' or Eschmeyer's scorpionfish or paddle-flap scorpionfish, is a species of marine ray-finned fish belonging to the Family (biology), family Scorpaenidae, the scorpionfishes. This species is found in the Indo-West Pacific. It grows to an average size of 16.6 cm in length. It occasionally makes its way into the aquarium trade. Although some have raised questions as to whether R. eschmeyeri is a morphological variant of ''Rhinopias frondosa'' rather than a separate species, a 2006 study by Motomura and Johnson confirmed the species' existence and distinguished it from other members of the genus ''Rhinopias''. Taxonomy ''Rhinopias eschmeyeri'' was first formally Species description, described in 1977 by the French speleologist and zoologist with the Type locality (biology), type locality given as Mahébourg on Mauritius. This species has been seen associating with ''Rhinopias frondosa, R. frondosa'' in pairs and it has been suggested that these are the di ...

Operculum (fish)
The operculum is a series of bones found in bony fish and chimaeras that serves as a facial support structure and a protective covering for the gills; it is also used for respiration and feeding. Anatomy The opercular series contains four bone segments known as the preoperculum, suboperculum, interoperculum and operculum. The preoperculum is a crescent-shaped structure that has a series of ridges directed posterodorsally to the organisms canal pores. The preoperculum can be located through an exposed condyle that is present immediately under its ventral margin; it also borders the operculum, suboperculum, and interoperculum posteriorly. The suboperculum is rectangular in shape in most bony fishy and is located ventral to the preoperculum and operculum components. It is the thinnest bone segment out of the opercular series and is located directly above the gills. The interoperculum is triangular shaped and borders the suboperculum posterodorsally and the preoperculum anterodorsa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinopias Cea
''Rhinopias cea'', or Cea's scorpionfish, is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. This species is only known from two sites in the southern Pacific Ocean. Taxonomy ''Rhinopias cea'' was first formally described in 1997 by the American biologists John E. Randall and Louis Henry DiSalvo Chalfant with the type locality is given as Motu Iti, Easter Island. The holotype was caught by hand in February 1985. The specific name honours the Chilean physician, SCUBA diver, photographer, filmmaker and spearfisherman Alfredo Cea Egaña in recognition of his contribution to the authors knowledge of the fishes of Easter Island. Description ''Rhinopias cea'' is similar to '' R. argoliba'' and shares a low dorsal fin and a low number of flaps and tentacles on the skin. The overall colour is reddish brown but differs from ''R. argoliba'' in being more mottled and in not possessing the white teardrop shaped mark between the eye and the ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...
