Preferred depth ranges were given as 73-90 and 128-144 m, temperatures of 6-10°C and salinities of 33-34 ppt. Feeds on herring, sand lance, alewives, menhaden, smelt, cod, haddock, mackerel, cunner, striped bass, sculpins, sea ravens, flounders, skates, crabs, squid, other molluscs, starfish, marine worms and seabirds.
