Occur over soft bottoms of the continental slope (Ref. 7300, 75154). Mainly feeds on small bony fishes (Ref. 114953). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205); egg cases ca. 19 cm long (Ref. 114953). This species reaches maturity at ca. 13 years. Length of mature males at ca. 120 cm TL; young hatch at ca. 26 cm TL (Ref. 114953).
生活在大陆斜坡的软质底部之上。 (参考文献 7300) 卵生的.(参考文献 50449) 卵在贝壳上有像触角一样的突出。 (参考文献 205)
