Grootte / Gewicht / Leeftijd

Maturity: L_m ? range ? - ? cm
Max length : 66.0 cm TL mannelijk / geslacht onbekend; (Ref. 114953)

Occur over soft bottoms of the continental shelf and slope (Ref. 7300, 75154). Mainly feeds on benthic crustaceans, small fishes and octopi (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 measure 7.0 cm long and 3.8 cm wide (Ref. 6778). This species reaches maturity after 5 years. Maturity size of males at ca. 45 cm TL; young hatch at ca. 11 cm TL (Ref. 114953). Utilized as a food fish (Ref. 6871).

Estimates based on models

Preferred temperature (Ref. 123201): 11.9 - 17, mean 14.5 °C (based on 78 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5010 [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).

Trofisch niveau (Ref. 69278): 4.2 ±0.7 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100).

Prijsklasse (Ref. 80766): Medium.
