Surgeonfish
Acanthuridae are the family of surgeonfishes, tangs, and unicornfishes. The family includes about 86 extant species of marine fish living in tropical seas, usually around coral reefs. Many of the species are brightly colored and popular in aquaria. Morphology The distinctive characteristic of the family is that they have scalpel-like modified scales, one or more on either side of the peduncle of the tail. The spines are dangerously sharp and may seriously injure anyone who carelessly handles such a fish. The dorsal, anal, and caudal fins are large, extending for most of the length of the body. The mouths are small and have a single row of teeth adapted to grazing on algae. Surgeonfishes sometimes feed as solitary individuals, but they often travel and feed in schools. Feeding in schools may be a mechanism for overwhelming the highly aggressive defense responses of small territorial damselfishes that vigorously guard small patches of algae on coral reefs. Most species ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sohal Surgeonfish
The sohal surgeonfish (''Acanthurus sohal'') or sohal tang, is an endemic from the Red Sea and Persian Gulf. A single record was reported in 2017 from the eastern Mediterranean Sea, a likely result of aquarium release. It can grow up to 16 in (40 cm) in the wild. It is a valued aquarium fish. Its striking blue and white horizontal stripes have made it for many the 'poster fish' for the Red Sea reef and Persian Gulf environment. Like other tangs, the sohal tang is compressed laterally, making it extremely maneuverable and fast along the reef. It has a horizontal, blade-like spine along the base of its tail on both sides, which folds into the fish, pointing anteriorly towards the head. During defense and aggression, tangs flick the spine at other fish or intruders, causing physical harm. The surgeonfish are named for this scalpel A scalpel, lancet, or bistoury is a small and extremely sharp bladed instrument used for surgery, anatomical dissection, podiatry and various ar ...

Whitemargin Unicornfish
The whitemargin unicornfish (''Naso annulatus'') is a tropical fish found throughout the Indo-Pacific. It can reach a length of 100 cm, making it one of the largest members of the family Acanthuridae. The species itself exists beyond the Pakistan coast, it can be found throughout different regions of the ocean, including Hawai’i and the Red Sea Description ''Naso annulatus'' also known as Whitemargin unicorn fish are one of many surgeon fish in the sea.

The tail is black surrounded by a white margin. It is often found in large schools off tropical reefs, and it feeds on zooplankton. The fish has two scutes on the left side. These are found on the caudal peduncle near the tail. Habitat & Biology White-margin Unicorn fish can be located in the shallow parts of the ocean, such as the coral reefs. I ...

Paracanthurus
''Paracanthurus hepatus'' is a species of Indo-Pacific surgeonfish. A popular fish in marine aquaria, it is the only member of the genus ''Paracanthurus''.

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sp ...

Naso (fish)
''Naso'' is a genus of fish in the surgeonfish family, Acanthuridae. Fish of this genus are known commonly as unicornfishes because of the "rostral protuberance", a hornlike extension of the forehead present in some species. Unicorn fish are popular with spearfishermen and may be cooked by grilling them whole. Unicornfish primarily live around coral reefs and eat mostly algae. It is very popular in Maldives. This genus is distributed across the Indo-Pacific from Africa to Hawaii. Species The 20 currently recognized species in this genus are: * ''Naso annulatus'' ( Quoy & Gaimard, 1825) – whitemargin unicornfish * ''Naso brachycentron'' (Valenciennes, 1835) – humpback unicornfish * ''Naso brevirostris'' (G. Cuvier, 1829) – short-nosed unicornfish, spotted unicornfish * '' Naso caeruleacauda'' J. E. Randall, 1994 – bluetail unicornfish, blue unicorn * '' Naso caesius'' J. E.
