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 5.6-6.0 cm long and 3.0 cm wide (Ref. 41249, 41253). Depth range given by H. Ishihara (pers.comm. 07/07).

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).

Estimates based on models
Preferred temperature (Ref. 123201): 17.7 - 22.5, mean 19.9 °C (based on 6 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 ±0.6 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 (37 of 100).
