Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 5; Anal soft rays: 5. Metamorphosed females distinguished by having an extremely large oblique mouth; elements of upper and lower jaws extending posteriorly far beyond the base of the pectoral fin and opercular opening; vomerine teeth present or absent; well developed sphenotic spines; well-developed symphisial spine on lower jaw; elongate and tapering angular, forming long narrow spine; hypomandibula with two heads; small quadrate spine, however, longer than articular spine; deeply notched posterior margin of opercle; short and broad subopercle, dorsal end rounded, ventral end nearly circular; toothless pharyngobranchial II; caudal fin lacking internal pigmentation; extremely short illicium, almost totally enveloped by tissue of esca in smaller specimens; well developed first ray of dorsal fin; dorsal fin rays 5; anal fin rays 5; short and broad pectoral fin lobe, shorter than longest rays of pectoral fin; pectoral fin rays 18-20; skin naked, lacking dermal spinules; darkly pigmented skin of caudal peduncle extends well past base of caudal fin (Ref. 86949).

Estimates based on models
Preferred temperature (Ref.
123201): 3.4 - 5.3, mean 4.5 °C (based on 371 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.

Trophic level (Ref.
69278): 3.4 ±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).
