Descripción breve
Claves de identificación | Morfología | Morfometría
Radios blandos dorsales (total) : 76 - 85; Radios blandos anales: 59 - 68; Vértebra: 43 - 45. Diagnosis: Vertebrae 11+32-34=43-45, dorsal fin rays 76-85, anal fin rays 59-68; eyes large (at least 2.5% SL); outer pseudoclasper large, broad, ear-lobe shaped; inner pseudoclasper a fleshy appendix at the anterior-inner rim of the outer pseudoclasper, without supporter; large scale patch on operculum above opercular spine (6–9 scales) and 1 to 3 isolated scales below opercular spine; head profile strongly ‘high-necked / hump-backed’; color yellow in live specimens (Ref. 57884).
Body shape (shape guide): elongated; Cross section: compressed.
Large dominating individuals were observed to make attacks toward smaller fish, which were hiding below rocks or any other shelter provided. One male was observed to flip backward the cover of the copulatory organ so that the organ can be exposed while swimming (Ref. 57884). Solitary inhabitant of coral reef crevices to at least 20m depth, cryptic (Ref 90102).
