Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 5 - 6; Anal soft rays: 4 - 5. Distinguishing characteristics of metamorphosed female: esca unusually large and laterally compressed esca, greatest width more than 1.5 times its length; terminal escal papilla, rounded; well developed posterior and anterior escal appendages, usually bearing 1 or more tiny, slender terminal filaments; upper jaw with 67-111teeth, lower jaw 51-68 teeth; vomerine teeth 6-10 (Ref. 86949).

Specimens trawled off from bottom at depth up to 1216 m (Ref. 86949).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6406 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.7 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
