Short description Morphology | Morphometrics

Dorsal soft rays (total): 18-21; Anal soft rays: 17 - 21; Vertebrae: 47. Body relatively deep, about 20%SL. Caudal peduncle moderately long (<18%SL). Vertical fin bases almost opposite to each other, the length of bases <20% SL. Head relatively deep and wide (eye width >10%SL). Snout relatively short, length not reaching orbit diameter; olfactory bulbs very big; ethmoid in olfactory bulb region very narrow. Eyes very large. Photophores present on the head, along the rays of the gill membrane and on the surface of the lower jaw seismosensory canals; also on the membranes of A,P, and V. Pyloric caeca < 10. (Ref. 36330).

Estimates based on models

Preferred temperature (Ref. 123201): 3.6 - 7.2, mean 4.9 °C (based on 465 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (31 of 100).
