Biology: |
Found inshore and offshore, on continental and insular shelves and adjacent deep water (Ref. 244). Common at bays, river mouths and in harbors; avoids sandy beaches and the surf zone, coral reefs and rough bottom, and surface waters (Ref. 244). Coastal-pelagic, but usually bottom associated at 1-280 m (Ref. 58302). Sometimes in oceanic waters (Ref. 9997). Known to make extended seasonal migrations in some parts of its range (Ref. 6871). Feeds mainly on bony fishes, also small sharks, cephalopods, and shrimps (Ref. 5578), rays and gastropods (Ref. 5213). Viviparous (Ref. 50449). Sexual dimorphism is evident in thickness of skin layer of maturing and adult females (Ref. 49562). Populations are segregated by age. Young readily kept in aquaria (Ref. 244). Utilized for human consumption, for leather and oil (Ref. 244). Marketed fresh, smoked, dried-salted and frozen; fins are valued for soup (Ref. 9987). Used in Chinese medicine (Ref. 12166). Records to 300 cm TL uncertain (Ref. 9997). TL to 300 cm (Ref. 26938).
