Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 16; Anal spines: 0; Anal soft rays: 15 - 19; Vertebrae: 36 - 38. 14-16 AO photophores; 9-12 tooth patches on the lower limb of the second gill arch; 34-38 lateral line organs (Ref. 36121). Pectoral fins relatively long and well developed in juveniles (easily visible in individuals up to about 6 cm SL), progressively becoming relatively shorter, with thicker rays, and covered by skin (in various stages of becoming vestigial between 5-8 cm SL). Adults (greater than 8 cm SL) with vestigial rays buried in skin and not externally visible unless skin abraded or otherwise torn (Ref. 36121).
Oceanic (Ref. 4479) and mesopelagic (Ref. 75154). Usually found below 500 m at night but shallower in upwelling regions.
