Biologi     Daftar kata (contoh epibenthic)

Found on the continental shelf (Ref. 6871, 75154). 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 5.7 cm long and 3.2 cm wide (Ref. 41308). Males reaches maturity at 43-48 cm TL. Biology poorly known; probably have suffered population declines in recent years (Ref. 114953).
