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 3.5-4.8 cm long and 2.5-3.0 cm wide (Ref. 41249, 41298).

Estimates based on models

Preferred temperature (Ref. 123201): 16 - 23.2, mean 21.8 °C (based on 14 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): 3.9 ±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): Low to moderate vulnerability (27 of 100).
