Abstract
The plgmentary responses to shade of background and temperature were examined in 2 Costa Rican species of fiddler crabs, Uca galapagensis herradurensis and U. zacae, and a temperate species, U. pugnax. The results were then compared with those published previously for U. pugilator, a 2nd temperate species. It was shown that the coloration of the crab is influenced simultaneously by a number of factors, including shade of background, light intensity, temperature, and rhythms, some of which are antagonistic and others supplementary, in their effects. The relative weights of these factors vary from species to species in a way which can be related to features of the habitat of the species, such as type of terrain and temperature.This publication has 1 reference indexed in Scilit:
