Supplementary material from "Coping with copepods: do right whales ( Eubalaena glacialis ) forage visually in dark waters?"
North Atlantic right whales ( Eubalaena glacialis ) feed during the spring and early summer in marine waters off the northeast coast of North America. Their food primarily consists of planktonic copepods, Calanus finmarchicus , which they consume in large numbers by ram filter feeding. The coastal w...
