Ecology of Cancer borealis
 
Main Ref. Tavares, M., 2003
Remarks Lives in deep water (Ref. 106868). Occurs from the intertidal zone among rocks to 800 m (Ref. 367). Common in shallow subtidal zone during summer (Ref. 106868). Small to medium-sized individuals are found near shore seasonally (especially in the south), while larger ones only occur in deeper water (Ref. 367). Moves from subtidal into low intertidal with the tide (Ref. 106868). Found in rocky bottom in association with Homarus americanus. Also on rubble and soft substrate (Ref. 97531). Feeds mainly on mollusks, echinoderms, and other invertebrates (Ref. 367). Preyed upon by gulls (Ref. 106868).
