Theoretical Considerations about Tapeta Lucida

Abstract

Many fishes employ a catoptric device, the tapetum lucidum, to increase light absorption by the retina. The ocular structure and habits of these fishes indicate that they are adapted to a mode of existence in dim light and that tapeta might aid vision under such circumstances by enhancing sensitivity. Unfortunately, little experimental evidence is available about the role of fish tapeta in vision, so even an indirect approach may contribute useful information.
