Biologie     Glossaire (ex. epibenthic)

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).
