Short description Morphology | Morphometrics

Dorsal spines (total): 1; Anal spines: 0; Anal soft rays: 0. Pale brown dorsally, grey-brown ventrally; snout and front of head white (Ref. 26346). A spookfish with a very long, narrow, conical snout, a small eye situated behind the mouth, a rather long first dorsal fin and spine, relatively smooth tooth plates, and with the lower caudal-fin lobe longer than the upper lobe (Ref. 6871).

Estimates based on models

Preferred temperature (Ref. 123201): 5 - 9.8, mean 7.1 °C (based on 517 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6289 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00100 (0.00062 - 0.00161), b=3.11 (2.97 - 3.25), in cm total length, based on LWR estimates for species & Subfamily-BS (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming Fec <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
