Biologie     Glossaire (ex. epibenthic)

Found on continental and insular shelves, mainly over sandy, shell, and coral bottoms. Feeds on small fishes, including pinfish (Sparidae) and porcupine fish. Preyed on by larger sharks. Viviparous (with a yolk-sac placenta), with 3 to 6 young per litter. Performs a 'hunch' display, with back arched, caudal lowered and head raised, as a possible threat display when confronted by divers. Utilized dried salted for human consumption. Minimum depth from Ref. 055176.
