Biología     Glosario (por ej. epibenthic)

Found on sand-mud bottoms of upper continental and insular slopes (Ref. 41299, Ref. 114953). Feed on invertebrates and bony fishes (Ref. 9908, Ref. 114953). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 22.0-23.5 cm long and 14.0-14.5 cm wide (Ref. 41249, 41253). A male holotype reaches maturity at 135 cm TL, females at 115 cm TL (Ref. 114953).

Estimates based on models

Preferred temperature (Ref. 123201): 3.6 - 5.6, mean 4.6 °C (based on 132 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  4.0   ±0.62 se; based on food items.
Resiliencia (Ref. 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
