Etymology: Diceratias: Greek, di = two, double + Greek, keras or keratos = horn, horned (referring to the two conspicuous dorsal-fin spines in the larvae and young females) (Ref. 86949); pileatus: From the Latin pileatus meaning capped, referring to the terminal papilla of the esca (Ref. 39830).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 5 - 7; Anal spines: 0; Anal soft rays: 4. Distinguishing characteristics of metamorphosed female: relatively small esca, width about equal to length; conspicuous bulbous posteriorly oriented terminal escal papilla; absence of posterior and anterior escal appendages; escal pore at posterobasal margin of terminal papilla; teeth in lower jaw 25-65, upper jaw with 27-82 teeth; vomerine teeth 4-14 (Ref. 86949).

Found near or on continental shelf, old specimens probably benthic (Ref. 6939). Bentho-, meso- and bathypelagic (Ref. 58302).

Estimates based on models

Preferred temperature (Ref. 123201): 2.5 - 9, mean 5.6 °C (based on 436 cells).

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): 4.1 ±0.7 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).
