Acanthuridae
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 are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 species normally range from a brownish-white color to grey/olive in color. They can be distinguished by the sharp cone like-shap "nasal" protruding out of their foreahead. 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 ...

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.

Fish Scale
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages. The term ''scale'' derives from the Old French , meaning a shell pod or husk. Scales vary enormously in size, shape, structure, and extent, ranging from strong and rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes. The morphology of a scale can be used to identify the species of fish it came from. Scales originated within the jawless ostracoderms, ancestors to all jawed fishes today. Most bony fishes are covered with the cycloid scales of salmon and carp, or the ctenoid scales of perch, or the ganoid scales of sturgeons and gars. Cartilaginous fishes (sharks and rays) are covered with placoid scales. Some species are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
