Found on the uppermost continental slope. Probably a dwarf species. Oviparous (Ref. 50499). This species could possibly attains a maximum size of 50.0 cm TL, with males reported (Ref. 26842) to reach length at maturity at 36.7 cm TL. A 45.0 cm female was found gravid and have two egg cases, one in each uterus, containing visible embryos (85.1-86.2 mm) with attached yolk sac. Stomach examined contains crustaceans and cephalopods (Ref. 95495).

栖息于最上面的大陆斜坡了。 可能一个矮小的种。 卵生的.(参考文献 50499)
