Scotopic electroretinogram of dogfish shark (Scylliorhinus canicula) and eel (Anguilla anguilla) is characterized by a negative off-response, changing in sign under photopic condition. It increased under the effect of increased background illumination, but its amplitude never exceeded that of the b-wave. On the other hand, dark-adapted electroretinograms of two perch-like species, perch (Perca fluviatilis) and painted comber (Serranus scriba), exhibited a positive off-wave, exceeding the b-wave amplitude under bright photopic conditions.
