Microspectrophotometric study of visual pigments in five species of geckos

Photoreceptors and visual pigments were studied by light microscopy and micro-spectrophotometry in geckos Teratoscincus scincus, Gymnodactylus russovi, G. caspius, G. fedchenkovi and G. kotschui. Type A single, type B double and the thicker members of type C double cells were found to contain a gree...

More Information
Summary:Photoreceptors and visual pigments were studied by light microscopy and micro-spectrophotometry in geckos Teratoscincus scincus, Gymnodactylus russovi, G. caspius, G. fedchenkovi and G. kotschui. Type A single, type B double and the thicker members of type C double cells were found to contain a green-sensitive visual pigment with the maximum absorption at 534–537 nm. Blue-absorbing pigment (λ m = 446–460 nm) was only found in the thinner members of type C doubles.
