Abstract
Under controlled exptl. conditions, the cave crayfish of Mammoth Cave, Kentucky, was generally photo-negative. This response was not a direct orientation but was accomplished by the trial-and-error method. Individuals of both sexes and of different sizes were used in an analysis of organismal activity. Recording apparatus used in this study is descr. Over 4000 animal exptl. hours are tabulated and analyzed. Under relatively constant temp., and in normal fluctuation of light and dark, constant darkness, constant light and reversed illumination, this species is arhythmic with respect to the 24-hr. day-night cycle. The bearing of these findings on cave biology is discussed.This publication has 4 references indexed in Scilit:
