Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 11 - 12; Raggi dorsali molli (totale) : 12; Spine anali: 2; Raggi anali molli: 11; Vertebre: 26. This species is distinguished by the following characters: with a rigid upper jaw lacking flexible lamina posteriorly, extending about 1.2 to 1.5 eye diameters behind posterior margin of orbit; infraorbitals are very broad and robust, the third infraorbital with no suborbital shelf; D XI-XII, 12 (usually XI,12); A II,11; vertebrae 10+16; scale rows in horizontal series 56-67; total gill rakers 41-44. Colouration: in life, body with 5-7 violet-blue stripes and head with prominent violet-blue blotches (Ref, 128653).
Cross section: compressed.
This species is probably a deep-water species, similar to its sister-species Opistognathus aurolineatus (reflected in the depth range given) (Ref. 128653). Mouthbrooders (Ref. 240).
