Biologie     Verklarende woordenlijst (b.v. epibenthic)

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. 115969): 14 - 27.2, mean 20.3 °C (based on 96 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00147 - 0.00681), b=3.22 (3.04 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.61 se; based on food items.
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Assuming fecundity<100).
Kwetsbaarheid (Ref. 59153):  High vulnerability (64 of 100) .
