Dorsal soft rays (total): 7 - 8; Anal soft rays: 5 - 6. Distinguishing characteristics of metamorphosed female: esca with single elongate internally pigmented anterior appendage, approximately one-fourth to nearly one-third length of escal bulb, trilobed distally with 3 round translucent windows; anterior escal appendage flanked laterally by an elongate unpigmented swelling; absence of medial escal appendages; posterior escal appendages with swollen basal portion and compressed distal crest, with terminal, anteriorly directed crescent-shaped filament and a pair of anterior lobes each bearing none to several filaments; 2-3 filamentous anterolateral escal appendage on each side; basal series of 7-12 filaments on each side; total number of teeth in upper jaw 25-51, lower jaw with 33-53 teeth; ratio between number of teeth in upper jaw to lower jaw teeth 0.76-0.98; vomerine teeth 4-8; length of illicium 32.8-47.4% SL; escal bulb width 4.5-6.5% SL (Ref. 86949).

Estimates based on models

Preferred temperature (Ref. 123201): 7.5 - 12.4, mean 9.3 °C (based on 50 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [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): 3.7 ±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).
