Biologi     Daftar kata (contoh epibenthic)

Occur from near shore to 183 m depth at temperatures ranging from 14 to 28° C but it is most common inshore of 91 m at 16-25°C. Young occur in shallow bays. Adults tend to live offshore (Ref. 26938). Adults feed mainly on decapod crustaceans and to a lesser extent on other benthic invertebrates and fishes. 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 6.3 cm long and 3.8 cm wide (Ref. 41359).
