Lengte bij maturiteit / Grootte / Gewicht / Leeftijd

Maturity: Lm 45.5, range 43 - 48 cm

Biologie     Verklarende woordenlijst (bv. epibenthic)

Found on the continental shelf (Ref. 6871, 75154). 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 5.7 cm long and 3.2 cm wide (Ref. 41308). Males reaches maturity at 43-48 cm TL. Biology poorly known; probably have suffered population declines in recent years (Ref. 114953).

Estimates based on models

Preferred temperature (Ref. 123201): 18.6 - 21.4, mean 20 °C (based on 8 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):  4.1   ±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 vulnerability (42 of 100).
