Morphology | Morphometrics
soft rays: 90. The head is relatively large; the eyes also large. Body tapers abruptly behind the first dorsal fin. Color is swarthy overall, pale ventrally. Back with 8 - 10 broad saddles or bars extending slightly below the lateral line. The fins are dusky except for the whitish outermost pelvic ray. The mouth and gill cavities gray to black.
Feeds mainly on copepods, polychaetes, benthic mollusks, arthropods, decapods and amphipods, echinoderms and fishes (myctophids and Maurolicus).

Bayesian length-weight: a=0.00224 (0.00099 - 0.00507), b=3.16 (2.97 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.9 ±0.2 se; based on diet studies.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (55 of 100) .
