Morphology | Morphometrics
soft rays: 9;
Vertebrae: 25. Well-developed opercular spine present. Body is noticeably flattened laterally, its greatest width is 70-80 percent of greatest depth. Length of the second spine on the first dorsal fin is 23-26 percent of head length (Ref. 31632). Eighth rib below tenth vertebra absent. Ctenoid scales on lateral line; about 12-14 transverse scales below lateral line. Eyes large, oval; mouth oblique (Ref. 35777).
A mesobenthic-pelagic species living mainly above the bottom (Ref. 31632). Found on or near continental slopes and seamounts.

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00248 - 0.01466), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
