Scorpidinae

Scorpis violacea

The brush perch ( Scorpidinae ), also called rock bream, are marine fish from the group perch relatives ( Percomorphaceae ). They are primarily in the central Pacific from the Philippines to Australia before. Neoscorpis lithophilus is the only species in the western Indian Ocean, and lives off the coast of southeastern Africa. Three species occur in the eastern Pacific off, Bathystethus orientale in Easter Island, Media Luna ancietae off the coast of Peru and Chile and Scorpis chilensis in the Juan Fernández Islands. They live on rocky shores and in kelp beds.

Features

Feger perches are 20 to 50 cm long, are generally high backs and have a continuous dorsal fin. In contrast to the rodent -like bass ( Girellinae ) they have no incisor -like teeth. What is striking is the symmetry between the dorsal and anal fin. The supported part of spines (9 or 10 spines ) of the dorsal fin is much lower than the supported by soft rays. The squamation extends over most of the worn sections of soft rays of dorsal and anal fin. The pelvic fins set clearly behind the pectoral fins.

System

The brush perch are generally regarded as subfamily the control perch ( Kyphosidae ) attributed ( Fishbase, Nelson, 2006). Some authors also give them the rank of a separate family ( carpenter, Kuiter ).

Genera and species

So far, 11 species have been described in four genera:

  • Genus Bathystethus Bathystethus cultratus ( Bloch & Schneider, 1801)
  • Bathystethus orientale Regan, 1913
  • Labracoglossa argenteiventris Peters, 1866
  • Labracoglossa nitida McCulloch & Waite, 1916
  • Media Luna ancietae Chirichigno, 1987
  • Media Luna californiensis ( Steindachner, 1876)
  • Scorpis aequipinnis Richardson, 1848
  • Scorpis chilensis Guichenot, 1848
  • Crescent ( Scorpis georgianus ) Valenciennes, 1832
  • Scorpis lineolata Kner, 1865
  • Scorpis violacea ( Hutton, 1873)

Formerly the subfamily associated genre Neoscorpis is now placed in the Kyphosinae, since the common features of Scorpidinae and Neoscorpis are plesiomorphic.
