Abstract
The results obtained from a study of the effect of intensity of illumination on the speed of progression of a number of marine invertebrates indicate that the activity of locomotor appendages, operated by muscles, is a function of the luminous intensity and that the animals move faster in light of high intensity than in light of low intensity. This, however, is not true of animals moving by means of cilia, for such animals, provided they move in a straight line in directional light, show no change in speed and hence no change in ciliary beat as the light intensity is varied.This publication has 4 references indexed in Scilit:
