Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 11; Radios blandos dorsales (total) : 18 - 20; Espinas anales: 3; Radios blandos anales: 8 - 10. Distinguished by the following characteristics: body and fins black with many large white blotches (Ref. 13608). Compressed, with a large pectoral fin; scales smooth (Ref. 26938); greatest depth of body 2.2-2.5 in SL; body width 2.2-2.9 times in depth; head length 2.5-2.8 times in SL; rounded preopercle, finely serrate, serrae at the angle slightly enlarged (Ref. 089707).

Biología     Glosario (por ej. epibenthic)

Usually on deep ledges, at depths to 210 m and on reefs, usually in caves or deep crevices (Ref. 7251). Solitary (Ref. 26340) and secretive, darts away when approached or frightened (Ref. 9710). Rarely seen in markets. Major threat to this species is fishing pressure (Ref. 089707).
