Abstract: Shell variables which influence shell selection in the laboratory were studied by multivariate analyses. Three shell variables important for hermit crabs, viz. volume, weight and aperture width, were employed against carapace length of crabs in the analyses. Scaled 1st principal component appeared to be a reliable estimator of shell size for this crab and when it had a choice, the crab preferred a shell of suitable general dimension rather than a shell based on any one particular variable.
