簡短描述 型態特徵 | 形態測量圖

Diagnosis: Body uniformly black, slightly brownish in larger specimens. Dermal denticles large and giving a rough texture to the skin. Upper labial furrows longer than the lower ones. First dorsal fin only slightly smaller than the second dorsal fin, originating from above anterior third to middle of the pelvic fin base. Second dorsal fin insertion just before level of anal fin insertion. Interorbital space 1.9-3.5 times eye horizontal diameter. Abdomen between pectoral fin tip and pelvic fin origin 1.3-2.5 times pectoral fin width. Spiral valves of the intestine 19-23 (mostly 21-22). Monospondylous + precaudal diplospondylous vertebrae 36-43 + 26-32 (often 38-40 + 28-30). Dermal denticles on tongue and palate absent (Ref. 56212).

Estimates based on models

Preferred temperature (Ref. 115969): 3.5 - 9.9, mean 7.2 °C (based on 79 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00148 - 0.00675), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  4.0   ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  非常低的, 最小族群倍增時間超過14 年 (Fec assumed to be <10).
瀕危性 (Ref. 59153):  Moderate to high vulnerability (50 of 100) .
