Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 53 - 58; Anal soft rays: 48 - 53; Vertebrae: 59 - 64. This species is characterized by the following: broad head; ventral and transverse mouth; smaller chin pores than mandibular pores and markedly approximated; opercular opening do not extend below 2nd and 3rd pectoral-fin rays; operculum about 1/3 HL; very large opercular lobe, extending far past of pectoral; rays of pectoral fin evenly decreasing in length without forming marked notch. Colour of peritoneum black, stomach dark brown to black (Ref. 44814).
A 1.45 cm SL fry was caught in the mesopelagic zone (Ref. 44814).
