Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 5; Espinhos anais: 0; Raios anais moles: 5. Metamorphosed females differ from all other Gigantactis congeners in having length of illicium 330% SL; escal bulb nearly spherical, with a short, truncated distal prolongation, pigmented distally, and bearing two pairs of short, spatulate appendages; stem of illicium without filaments (Ref. 41361); short dentary teeth (longest tooth 1.7% SL), arranged posteriorly in two longitudinal series; longest caudal fin rays 50% SL (Ref. 86949).

Known only from the holotype collected in an open midwater trawl (Ref. 41361). Maximum length based on an immature female (Ref. 41361).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [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).

Nível Trófico (Ref. 69278): 3.8 ±0.7 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
