Size / Peso / Age

Maturity: L_m ? range ? - ? cm
Max length : 115 cm TL maschio/sesso non determinato; (Ref. 114953)

Commonly found near coast. Demersal on inner continental shelf. Feeds mainly on fishes, crustaceans and cephalopods (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 14.5-16.0 cm long and 7.0-7.5 cm wide (Ref. 41249, 41253, 41298). Males reaches maturity at ca. 47 cm TL, females at ca. 69 cm TL; young hatch at 9-10 cm TL (Ref. 114953).

Life cycle and mating behavior Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 5.5 - 22.3, mean 16.8 °C (based on 53 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00282 (0.00162 - 0.00491), b=3.26 (3.12 - 3.40), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.4 ±0.7 se; based on diet studies.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (69 of 100).
