Epibenthic, in deep waters down to 2740 (Ref. 58426). Adults are commonly found in about 300-500 m depth. Temperature preferences appear to range from about 1-4°C, although bottom temperatures below 0°C have been recorded at capture depths. Amphipods predominate in the diet, although polychaetes and various natant crustaceans are also important. Also feed on bivalves, isopods, echinoderms (notably ophiuroids), and ctenophores (Ref. 1371). Batch spawner (Ref. 51846).
普遍地栖息于大约 300-500 公尺深。 温度偏爱似乎范围从到处 1 - 4 °C,虽然底部温度低于 0 °C 曾经在抓取深度记录。 片脚类动物在食性中成为主流,虽然多毛类而各种不同的漂浮甲壳动物也是重要的。 也吃二枚贝，等足目动物，棘皮动物 (特别地阳燧足) 与栉水母。
