Determinatiesleutels | Morfologie | Morfometrie
Dorsale zachte stralen (totaal) : 12 - 13; Anale zachte stralen: 16. Three equidimensional spiny rays present on the posttemporal spine. In front of the dorsal fin is a long, pigmented protuberance, reaching to the median line of the body. Photophores in the anal series few, 8-9. A wide gap equal to the length of the group of subcaudal photophores present between the anal and subcaudal photophores. Spiny scales absent on preanal, anal and subcaudal photophores. Trunk relatively deep body; caudal peduncle narrow (Ref. 26037).
Body shape (shape guide): short and / or deep.
