زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

Found on continental and insular shelves, as well as upper slopes. Feeds mainly on small benthic invertebrates (Ref. 114953). Oviparous (Ref. 205). Reaches maturity at 80-90 cm TL; birth size at ca. 20 cm TL (Ref. 114953). 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 capsule measures 116.5 mm long and 80.0 mm wide (Ref. 41249). Utilized as fishmeal and possibly not utilized for human consumption due to extreme roughness of its squamation (Ref. 5159).
