摘要: Abstract 1. Harp ( Pagophilus groenlandicus ) and harbour Phoca vitulina seals had rod visual pigments with λ max of 496–497 nm. Grey Halichoerus grypus a similar, if not identical pigment. 2. The pigment from the northern fur seal Callorhinus ursinus appeared to have near 500 3. Limited evidence available date suggests that pigments, like those fish whales, are probably adapted for vision in their respective photic environments.
