Korte beschrijving
Morfologie | Morfometrie
Dorsale stekels (totaal): 2; Dorsale zachte stralen (totaal): 124-125; Anale stekels 0; Anale zachte stralen: 110. Eyes relatively large. Snout short, moderately pointed, usually somewhat rounded with a high dorsal profile in adults, but often with prominent tubercles at its tip and lateral angles. Mouth large, lips thin. Underside of the head generally covered with small scales. Pyloric caeca 18 to 28. Overall color dark brown to swarthy in most individuals, but some are much paler; fins and lips blackish (Ref. 1371).
Remains of natant crustaceans (especially euphausiids), polychaetes, and fish (gonostomatids) have been found in the stomachs of three specimens examined.
