Occurs on sandy and muddy bottoms of outer continental shelf and upper slope, also found at shallower depth 20m. Feeds mainly on bony fishes and crustaceans (Ref. 114953). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205); egg cases ca. 20-30 cm long (Ref. 114953). Reaches maturity at ca. 13 years (Ref. 114953).

Estimates based on models

Preferred temperature (Ref. 123201): 4.7 - 12.2, mean 6 °C (based on 124 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00234 (0.00159 - 0.00346), b=3.18 (3.06 - 3.30), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.6 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

kategori harga (Ref. 80766): Medium.
