Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 13 - 15; Raios dorsais moles (total) : 15 - 18; Espinhos anais: 0; Raios anais moles: 15 - 18; Vértebras: 32. Skin very rough, scales interspersed with spinous bony tubercles. Mid-ventral (abdominal) keel on the ventral contour. Body is uniformly brown to dark brown, tips of the pectoral and pelvic fins black, margins of the second dorsal and anal fins white in young specimens.

Usually over the continental shelf, sometimes in oceanic waters down to 800 m (Ref. 9302). Usually solitary or in pairs near the bottom (Ref. 6181). Migrates far offshore (Ref. 26139). Pelagic (Ref. 5951). Feeds on fish, crustaceans and squid (Ref. 6181). The peculiar wooden 'palu' or Ruvettus hook is used to catch this species in south central Pacific (Ref. 6181). The flesh is very oily, with purgative properties, if eaten much (Ref. 6181). Marketed fresh and as fish cakes in Japan (Ref. 9302); also processed into fishmeal (Ref. 5217). Maximum length reported to reach up to 2 m only (Heemstra, pers. comm. 03/03).

Estimates based on models

Preferred temperature (Ref. 115969): 8.6 - 19, mean 12.9 (based on 603 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00347 (0.00191 - 0.00629), b=3.10 (2.93 - 3.27), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nível Trófico (Ref. 69278): 4.2 ±0.57 se; based on food items.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Assuming tm>4).

Prior r = 0.28, 95% CL = 0.19 - 0.42, Based on 1 data-limited stock assessment.
