Xanthichthys ringens, the Sargassum triggerfish, is a species of triggerfish from the Western Atlantic, ranging from North Carolina (USA) to Brazil.
Also known as the Redtail triggerfish, Xanthichthys ringens is often found in the Western Atlantic, ranging from South Carolina, through Gulf of Mexico to Lesser Antilles and Brazil. It lives in Tropical marine reefs at depths of 25 to 80 meters (82 to 262.5 ft). It generally reaching a size of 25 cm (9.8 in).
Xanthichthys ringens has three dorsal spines, 26–29 dorsal soft rays, and 23–27 anal soft rays. Its coloration includes three silvery-blue prominent diagonal grooves from below and behind mouth running nearly to gill opening, appearing as light brownish gray to a light blue with rows of dark spots on body. The caudal (tail) fin is pale with orange-red margins and a large orange-red crescent at the end of the tail.
Xanthichthys ringens inhabits seaward reef slopes, usually well below 30 m, where in some places they are among the most common fish, solitary or in small groups. Spawns in deep water young live among floating Sargassum, hence the name of Sargassum triggerfish. The fish feeds on crabs, shrimp, sea urchins and zooplankton.
Like other members of triggerfish, the sargassum triggerfish occasionally makes its way into the aquarium trade.
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, are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered.
The orange-lined triggerfish is a demersal triggerfish. Although Balistapus is a monotypic genus, it is closely related to the genus Balistoides.
The blue runner, also known as the bluestripe jack, Egyptian scad, hardtail jack or hardnose, is a common species of moderately large marine fish classified in the jack family, Carangidae. The blue runner is distributed across the Atlantic Ocean, ranging from Brazil to Canada in the western Atlantic and from Angola to Great Britain including the Mediterranean in the east Atlantic. The blue runner is distinguished from similar species by several morphological features, including the extent of the upper jaw, gill raker count and lateral line scale counts. The blue runner is known to reach a maximum length of 70 cm and 5.05 kg in weight, but is much more common below 35 cm. The species inhabits both inshore and offshore environments, predominantly over reefs, however it is known to congregate around large, man-made, offshore structures such as oil platforms. Juveniles tend to inhabit shallower reef and lagoon waters, before moving to deeper waters as adults.
The sargassum fish, anglerfish, or frog fish is a frogfish of the family Antennariidae, the only species in its genus. It lives among Sargassum seaweed which floats in subtropical oceans. The scientific name comes from the Latin histrio meaning a stage player or actor and refers to the fish's feeding behaviour.
The yellowtail snapper is an abundant species of snapper native to the western Atlantic Ocean including the Gulf of Mexico and the Caribbean Sea. Although they have been found as far north as Massachusetts, their normal range is along Florida south to the West Indies and Brazil. This species is mostly found around coral reefs, but may be found in other habitats. They occur at depths of from near the surface to 180 meters (590 ft), though mostly between 10 and 70 m. This species can reach a length of 86.3 cm (34.0 in), though most do not exceed 40 cm (16 in). The greatest weight recorded for this species is 4.98 kg (11.0 lb). Yellowtail snapper is a commercially important species and has been farmed. It is sought as a game fish by recreational anglers and is a popular species for display in public aquaria. This species is the only known member of its genus.
The royal angelfish, or regal angelfish, is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae, and the monotypic genus Pygoplites. It is found in tropical Indo-Pacific oceans. It can grow as long as 25 cm.
The grey triggerfish, or gray triggerfish, is a species of ray-finned fish in the triggerfish family. The species is native to shallow parts of the western Atlantic from Nova Scotia to Argentina and also the eastern Atlantic, the Mediterranean Sea and off Angola on the west coast of Africa.
The queen angelfish, also known as the blue angelfish, golden angelfish, or yellow angelfish, is a species of marine angelfish found in the western Atlantic Ocean. It is a benthic warm-water species that lives in coral reefs. It is recognized by its blue and yellow coloration and a distinctive spot or "crown" on its forehead. This crown distinguishes it from the closely related and similar-looking Bermuda blue angelfish, with which it overlaps in range and can interbreed.
Acanthurus bahianus, the ocean surgeon or ocean surgeonfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs. This species is found on reefs in the Atlantic Ocean off the coast of Brazil. It is sometimes marketed as a food item, but it is more often used as bait, or in tropical saltwater aquaria.
The bar jack, also known as the carbonero, red jack, blue-striped cavalla or passing jack, is a common species of inshore marine fish classified in the jack family, Carangidae. The bar jack is distributed through the western Atlantic Ocean from New Jersey and Bermuda in the north to Venezuela and possibly Brazil in the south, with the largest population in the Gulf of Mexico and West Indies. The bar jack is most simply distinguished from similar jacks by its dark horizontal bar which runs along the back and down the caudal fin, often accompanied by an electric blue stripe immediately below it. Other more detailed differences include dentition and soft ray counts. The bar jack is a moderately large species, growing to a recorded maximum of 65 cm and a weight of 6.8 kg. The species inhabits clear shallow waters, often over coral reefs where it lives either solitarily or in large schools, taking various fishes, crustaceans and cephalopods as prey. Studies in Cuba indicate spawning occurs between March and August, with sexual maturity reached at 26 cm. It is a relatively popular sport fish and can be caught on light tackle with a variety of lures and baits. It is considered to be a good food fish, however many recorded ciguatera cases are attributed to the species, with most cases reported on the island of St. Thomas traced to this single species.
Cephalopholis fulva, the coney or the butterfish, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is in the family Serranidae which also includes the anthias and sea basses. It is found in the western Atlantic. It is associated with reefs and is a quarry species for commercial and recreational fisheries. It can be found in the aquarium trade.
The blackbelly triggerfish 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.
Xanthichthys mento, the redtail triggerfish, blue-throat triggerfish, or crosshatch triggerfish, is a species of triggerfish from the Pacific. It inhabits outer-reef areas at depths of 6–131 m (20–430 ft), and feeds on zooplankton. Xanthichthys mento grows to a size of 29 cm (11 in) in length and occasionally makes its way into the aquarium trade.
Aluterus schoepfii, the orange filefish, is a species of fish in the family Monacanthidae. The species can also be listed under the family Balistidae. They can reach a maximum size of 62 centimetres (24 in) although they are common to 40 centimetres (16 in).
