Korte beschrijving
Determinatiesleutels | Morfologie | Morfometrie
Dorsale zachte stralen (totaal) : 14 - 16; Anale zachte stralen: 14 - 19. This species differs from other species in the subgenus Photonectes in the following set of characters: blue luminous tissue in a band extending from pectoral region to pelvic fins; with short transverse streaks between OV photophores, and in patches on sides of isthmus, under lower jaw and above end of maxillary; very long gill filaments very long, extending beyond opercular opening; shorter barbel than head length, with small bulb ending in a terminal appendage with a tiny bulb at tip (Ref. 92891).
Meso- and bathypelagic (Ref. 58302).
