The reactions of normal and eyeless amphibian larvae to light

Abstract

A great deal has been written about the photic reactions of amphibians, but this has been concerned chiefly with the adults, the larval forms having received but scant notice.In the spring of 1913 a series of experiments were carried out upon the larvae of Rana pipiens, R. sylvatica, and Amblystoma punctatum to determine whether they were sensitive to light, and if so, whether they were sensitive to light received through the skin as well as to light received through the eyes.
