Biology
Oviparous, with one egg laid per oviduct at a time [536]. Embryos feed solely on yolk [733]. Found on the outer continental shelf and upper slope, on or near the bottom [517]. May occur in shallower water in the temperate region than off tropical and subtropical areas. Feeds mainly on pelagic bony fishes, also fish offal, hagfish eggs, crustaceans, and cephalopods [536].
