Occurs on sandy and muddy bottoms of outer continental shelf and upper slope, also found at shallower depth 20m. Feeds mainly on bony fishes and crustaceans (Ref. 114953). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205); egg cases ca. 20-30 cm long (Ref. 114953). Reaches maturity at ca. 13 years (Ref. 114953).
卵生的.(參考文獻 50449) 卵在貝殼上有像觸角一樣的突出。 (參考文獻 205)
