Biologie     Verklarende woordenlijst (bv. epibenthic)

Occur in the sublittoral zone, 70-90 m on sandy mud bottoms (Ref. 11230). 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 6.1 cm long and 3.7 cm wide (Ref. 41249). Utilization details sketchy (Ref. 9908). Very rarely caught by demersal longline fisheries off Java. Utilized for its meat (Ref.58048).

Estimates based on models

Preferred temperature (Ref. 123201): 11.5 - 27.2, mean 24.7 °C (based on 98 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5001   [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):  4.0   ±0.60 se; based on food items.
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100).
