生态学
海洋 深海区的; 深度上下限 700 - 3000 m (Ref. 4449), usually 1500 - 2000 m (Ref. 4449). 深水域; 45°N - 35°S, 98°W - 20°E
Eastern Atlantic: off Morocco, the Azores and Canary Islands and South Africa. Western Atlantic: New Jersey, USA to the Gulf of Mexico and Caribbean. The record from Davis Strait probably refers to Polyacanthonotus rissoanus.
