Twentynine species of crabs encountered along the shores of the Pulicat lake have been surveyed with special reference to their vertical distribution, zonation of discrete patches, seasonal variation in population densities and the extent of their penetration into the lake. Specific association between vertical range and moisture content of the soil, zonation of discrete patches and composition of the substratum and reduction in number or total disappearance of crabs and lowering of salinity caused by monsoonal floods were discussed.
