Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 3; Anal spines: 0; Anal soft rays: 3. Mature females are unpigmented and have a nearly rounded shape of body. There are spines above the eyes and behind the mouth. The illicium consists of a rounded flap without pole. Small numerous teeth in both jaws (Ref. 557). Free lining males are characterized by: having weak sphenotic spines, nearly absent; slender and angled preopercle; moderately elevated epiotic region of skull; well developed premaxillae; 20-24 teeth on each side of upper and lower jaws (Ref. 86949).

Biology     Glossary (e.g. epibenthic)

Also mesopelagic (Ref. 7300). A small deep-sea angler fish. Males dwarfed, becoming parasitic on females (Ref. 10762). An 8 cm female was found with 3 parasitic males of 18 mm length, attached to her ventral side. Adult (=parasitic) males are colorless with reduced teeth, jaws, and eyes. Information on the maximum length of female was taken from Ref. 10762.

Estimates based on models

Preferred temperature (Ref. 123201): 3.9 - 10.8, mean 6.6 °C (based on 1085 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [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):  4.0   ±0.7 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
