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).
