Rhinecanthus
''Rhinecanthus'' is a triggerfish genus from the Indo-Pacific. They are found at reefs, and all except ''R. abyssus'' are restricted to relatively shallow depths. They are among the smallest members of the family, with no species surpassing in length. They are primarily brownish, greyish and white, and have strongly contrasingly patterns in yellow, orange, blue or black. Adults of all have a relatively dark line (in most species intermixed with blue) that extends from the forehead down through the eye to the pectoral fin Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as ....

Rhinecanthus Lunula
''Rhinecanthus lunula'', commonly known as the halfmoon picassofish, is a balistid triggerfish species first described by John E. Randall and Roger C. Steene in 1983. It belongs to the Indo-Pacific triggerfish genus ''Rhinecanthus''. Physical description While the standard length of ''Rhinecanthus lunula'' holotype is , the standard length of other type specimens ranges from . ''R. lunula'' can be differentiated from other ''Rhinecanthus'' species by its soft ray count and distinct coloration. It usually has 26 soft dorsal rays (though sometimes only 25 are observed), between 22 and 24 anal soft rays, and 14 pectoral rays. The longest dorsal soft ray is 11.7 percent of the standard length. A broad, black bar exists on the caudal peduncle. Anterior to the caudal peduncle is a curved black line which gives the species its name “lunula,” the Latin word for crescent. An orange-yellow band starts from the base of the upper lip and extends across the head to the pectoral base. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reef Triggerfish
The reef triggerfish (''Rhinecanthus rectangulus''), also known as the rectangular triggerfish, wedgetail triggerfish or by its Hawaiian name humuhumunukunukuāpuaa (, meaning 'triggerfish with a snout like a pig', also spelled humuhumunukunukuapua'a or just humuhumu for short), is one of several species of triggerfish. It is found at reefs in the Indo-Pacific and is the state fish of Hawaii. The name humuhumunukunukuāpuaa serves for both singular and plural descriptions. The fish shares its Hawaiian name with the lagoon triggerfish (''R. aculeatus''), another fish also found in the Indo-Pacific. Description The triggerfish's teeth and top lip are blue and the teeth are set close together inside its relatively plump mouth. It has a small second dorsal spine which is used to lock its main spine into an upright position. When sheltering in a small crevice, this locking of its spine helps protect the fish against being extracted by a predator. When fleeing from predators, it som ...

Rhinecanthus Assasi
''Rhinecanthus assasi'', commonly known as the Assasi triggerfish or Arabian picassofish, is a species of fish in the family Balistidae, the triggerfishes. Description ''Rhinecanthus assasi'' reaches up to 30 centimeters long. It is tan above and white below with blue stripes between and below the eyes. It feeds mostly on invertebrates. Habitat and distribution ''R. assasi'' mostly lives in or near coral reefs. It occurs in the western Indian Ocean, including the Red Sea and Persian Gulf The Persian Gulf ( fa, خلیج فارس, translit=xalij-e fârs, lit=Gulf of Persis, Fars, ), sometimes called the ( ar, اَلْخَلِيْجُ ٱلْعَرَبِيُّ, Al-Khalīj al-ˁArabī), is a Mediterranean sea (oceanography), me ....

Rhinecanthus Verrucosus
The blackbelly triggerfish (''Rhinecanthus verrucosus'') is a ray-finned fish in the family Balistidae found in the Indo-Pacific. It occasionally makes its way into the aquarium trade. It is sometimes known as the blackpatch triggerfish. Description The blackbelly triggerfish has a laterally compressed, deep body and a long snout. In shape it is rhomboidal and it grows to a maximum length of . The mouth is at the tip of the snout and the eye is set high on a long, straight forehead. The upper half of the body is pale brown and the underparts are white. There is a dark brown streak below the eye and a very large black spot on the underside just anterior to the anal fin. There are three short rows of forward pointing spines on the caudal peduncle. The anterior part of the dorsal fin consists of three spines which can be retracted into a groove and the separate posterior part has 23–26 soft rays. The anal fin is very much the same shape as the posterior dorsal fin and has 21–2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinecanthus Aculeatus
The lagoon triggerfish (''Rhinecanthus aculeatus''), also known as the blackbar triggerfish, the Picasso triggerfish, or the Picassofish, is a triggerfish, up to 30 cm in length, found on reefs in the Indo-Pacific region. The Hawaiian name for the fish, (), also spelled humuhumu-nukunuku-a-puaa or just humuhumu for short (meaning "triggerfish with a snout like a pig") is shared with the reef triggerfish (''R. rectangulus''), the state fish of Hawaii. This species has been studied in a range of research contexts, from locomotion to color vision research. Behavior Lagoon triggerfish live in the reefs and sandy areas of coral reefs, where they eat just about anything that comes along, mostly including invertebrates and reef algae. They are always restlessly swimming around and vigorously protect their territory against intruders, including divers, especially when guarding their eggs during reproduction season. Their relatively small size makes them much less dangerous than t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Triggerfish
Triggerfish are about 40 species of often brightly colored fish of the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the oceanic triggerfish (''Canthidermis maculata''), are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered. Anatomy and appearance The largest member of the family, the stone triggerfish (''Pseudobalistes naufragium'') reaches , but most species have a maximum length between . Triggerfish have an oval-shaped, highly compressed body. The head is large, terminating in a small but strong-jawed mouth with teeth adapted for crushing shells. The eyes are small, set far back from the mouth, at the top of the head. The anterior dorsal fin is reduced to a set of th ...

Blackpatch Triggerfish (Rhinecanthus Verrucosus) (42586038625)
Blackpatch is an archaeological site in West Sussex, England, about west of the village of Findon and about north-west of Worthing. It is the site of a Neolithic flint mine, and Bronze Age barrows. The site is a scheduled monument. Description Flint mine The flint mine, which was levelled about 1950, is on the south-west slope of Blackpatch Hill. There are more than 64 infilled shafts, diameter up to . The shafts and other features at the site were investigated from 1922 to 1932 by John Pull. Seven shafts were excavated. They were up to deep; from them, galleries extended up to , following a single seam of flint. Flint flakes and pottery sherds were found in the infills from the shafts. Around the shafts were working areas where mined flint was processed. An antler pick from a shaft has been radiocarbon dated to about 3000 BC.
