Visual predation during springtime foraging of the North Atlantic right whale ( Eubalaena glacialis )
Abstract To assess the role that vision plays in the ability of the North Atlantic right whale ( Eubalaena glacialis ) to detect its primary prey species, the calanoid copepod Calanus finmarchicus , we have compared the absorbance spectrum of the E. glacialis rod visual pigment, the transmittance sp...
