deskripsi pendek
Morfologi | Morfometrik
Grey in color; diamond-shaped and without large thorns on body or tail (Ref. 26346).
Found in deepwater on lower parts of continental slopes, on submarine rises and on deep-sea plains adjacent to both (Ref. 3167). Feeds mainly on fishes, with a small amount of shrimps (Ref. 3167). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Minimum depth reported taken from Ref. 3167.
Oviparous (Ref. 3167). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models
Preferred temperature (Ref.
123201): 3.6 - 6.1, mean 4.3 °C (based on 43 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00253 - 0.01042), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.69 se; based on food items.
Daya lenting (Ref.
120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Fec assumed to be <100).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (90 of 100).
