Found in deepwater on lower parts of continental slopes, on submarine rises and on deep-sea plains adjacent to both (Ref. 3167). Feeds mainly on fishes, with a small amount of shrimps (Ref. 3167). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Minimum depth reported taken from Ref. 3167.
