Sea chub

Kyphosus sp.

The control perch ( Kyphosidae ), also known as pilot or rudder perch perch, live in the Atlantic and Indo-Pacific, usually in temperate zones, such as the coasts of South Australia, but also in tropical regions.

Features

Control perch are depending on the type, 15 to 90 inches long. You have 24 to 28 vertebrae, only Graus nigra, there are 34 Like the butterfly fish, they have a narrow, high-backed body and a terminal with many small teeth mouth occupied. Especially the species of the subfamily Microcanthinae see butterfly fish confusingly similar ( Scorpidinae ) are similar while the types of rock bream the sea bream ( Bramidae ), and the types of Stevenage perch ( Girellinae ) and the authentics control perch ( Kyphosinae ) are reminiscent of rabbit fish ( Siganidae ).

  • Fins formula: Dorsal IX-XVI/11-28, Anal III/10-28.

The species of the subfamilies Girellinae and Kyphosinae with the exception of the genus gray herbivores that usually graze algae nursery. All other species eat ground-dwelling invertebrates.

Control perch are free spawners and congregate to breed in large flocks on steep reef walls. The juveniles initially live in mangrove areas, algae meadows, or you are under floating algae stocks or other floating debris before they join the swarms of adults.

System

The control perch are divided into four subfamilies ( Fishbase ), the control perch in the narrow sense ( Kyphosinae ), the Nage perch ( Girellinae ), the stripe butterfly fish ( Microcanthinae ) and brush perch ( Scorpidinae ). Nelson also represents the South African perch fish Parascorpis typus in the family of control perch ( subfamily Parascorpidinae ). Usually he will be allocated a separate family. Some authors give all subfamilies taxonomic families (Carpenter, Kuiter ), Betancur -R. and staff take this step in their nines classification of bony fishes only for Stevenage perch ( Girellidae ).

The following are the 14 species of the subfamily Kyphosinae are enumerated, which consists for a revision only of the genera Kyphosus and Neoscorpis. The other subfamilies are presented in separate articles.

  • Genus Kyphosus Lacepede, 1801 Kyphosus atlanticus Sakai & Nakabo, 2014.
  • Kyphosus azureus ( Jenkins & Evermann, 1889). ( Syn: Hermosilla azurea )
  • Kyphosus bigibbus Lacépède, 1801
  • High fin control perch ( Kyphosus cinerascens ) ( Forsskål, 1775)
  • Western control perch ( Kyphosus Cornelii ) ( Whitley, 1944)
  • Cortez control perch ( Kyphosus elegans) (Peters, 1869)
  • Kyphosus gladius Knudsen & Clements, 2013
  • Kyphosus hawaiiensis Sakai & Nakabo, 2004
  • Kyphosus Ocyurus ( Jordan & Gilbert, 1882) (syn.: Sectator Ocyurus )
  • Kyphosus pacificus Sakai & Nakabo, 2004
  • Kyphosus sectatrix (Linnaeus, 1758)
  • Buffalo control perch ( Kyphosus sydneyanus ) ( Günther, 1886)
  • Brass control perch ( Kyphosus vaigiensis ) ( Quoy & Gaimard, 1825)
  • Neoscorpis lithophilus ( Gilchrist & Thompson, 1908)

The control perch i.w.S. are probably not monophyletic, their core group ( control perch in the narrow sense ( Kyphosinae ) ) but with the Nage perch ( Girellinae ) related and form with them and the beak perch ( Oplegnathidae ), the Grunzbarschen ( Terapontidae ) and flag tails ( Kuhliidae ) a monophyletic group in the new systematics of the bony fishes by R. Betancur -R. et al. (2013 ) is classified as an order Terapontiformes. Whether stripe butterfly fish and brush perch to belong, further research must be clarified.
