Maturity: L_m ? range ? - ? cm
Max length : 113 cm TL mannelijk / geslacht onbekend; (Ref. 114953)

Found on sand-mud bottoms (Ref. 41299). Depth range from 80 m-150 m (Ref. 41299). Feeds on invertebrates and bony fish (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 8.5-10.0 cm long and 5.5-6.4 cm wide (Ref. 41249 , 41253).

Estimates based on models

Preferred temperature (Ref. 123201): 14 - 27.2, mean 20.3 °C (based on 96 cells).

Fylogenetische diversiteitsindex (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).

Trofisch niveau (Ref. 69278): 4.0 ±0.61 se; based on food items.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (68 of 100).
