Main Ref. Coad, B.W. and J.D. Reist, 2004
Remarks A very rare species inhabiting continental slopes and probably down to the abyssal plains (Ref. 3167). Benthic (Refs. 58426, 117245). Adults usually at depths greater than 1,500 m while juveniles are mainly taken from about 450 m downward (Ref. 4426). Minimum depth reported taken from Ref. 4426. Feeds on crustaceans (Ref. 58426). Dwells on continental slopes to bathyal depths from 475-1570m. Found in water temperatures between 3°C to 4.5°C. Feeds at a trophic level of 3.7 (Ref. 117245).
