Found on sand-mud bottoms (Ref. 41299). 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 13.0-14.6 cm long and 6.0-8.0 cm wide (Ref. 41249, 41253).

Estimates based on models

Preferred temperature (Ref. 115969): 0.6 - 1.2, mean 0.9 (based on 5 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
مستوى غذائي (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
المرونه (Ref. 120179):  منخفض, الحد الزمني الأدني لتضاعف عدد أفراد المجتمع 4.5-14 سنة (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100).
