Spectral Sensitivity and Color Vision in Skipjack Tuna and Related Species

Abstract

No chromaticity-type S-potentials were recorded from the retina of skipjack tuna and two other related species. This, together with a maximal response at about 497 nanometers from the only spectral pattern of the luminosity type, indicates that the species are probably color-blind. Ganglia cell responses and electroretiongrams also supported this view. © 1972, The Japanese Society of Fisheries Science. All rights reserved.
