The growth patterns in Uca tangeri, Seserma huzardi and Cardisoma armatum are discussed. The male : female ratios differ from 3 : 1 in S. huzardi to 2 : 1 in U. tangari. The males have equal proportions of right and left-handed individuals. Males are generally larger than females and have bigger major chelae. The relationship between carapace and chelae measurements were linear with unimodal and bimodal distributions corresponding to changes in shape of carapace and chelae of different size groups. The chelae of females change a little after maturity but in males, the level of allometry becomes stronger with increase in size. Relative growth rates showed greater correlation coefficients with length rather than weight. The condition factor was influenced by sex in U. tangeri and S. huzardi but by size in C. armatum.
