Ecologia de Homarus americanus
 
Ref. principal Holthuis, L.B., 1991
Notas Benthic in coastal and shelf waters (Ref. 106894). Possibly a selective feeder, preying mainly on crabs, echinoderms, mussels and polychaetes but also ingesting algae and seaweeds, with a complex foraging behavior and thus capable of maintaining gross diet composition despite of sharp variations in prey availability, seasonality and ontogenetic changes, e.g., molt- and size-related diet shifts (Ref. 33024). Migration does not occur, or only to a limited scale (Ref. 4).
