Tamanho / Peso / Idade

Maturity: L_m ? range ? - ? cm
Max length : 59.0 cm TL macho/indeterminado; (Ref. 13608); 69.0 cm WD (female)

Inhabits mud-bottom habitat on the upper slope, generally in waters deeper than 350 meters. Mainly feeds on small bony fishes (Ref. 114953). Stomach contents include one specimen of Mullus argentinae, remains of a teleost fish and predominance of Myctophidae fishes. Sympatric with other chondrichthyans, Etmopterus bigelowi, Squalus aff. blainvillei, and Dipturus leptocauda (Ref. 56543). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 5.5 - 13, mean 8 °C (based on 76 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 4.5 ±0.80 se; based on food items.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
