Total body water contents (percent of the total body fresh mass; mean ± S.E.M.) of the four species following losses of 0, 5, 10, 15 and 20% of initial mass. Asterisks indicate significant differences from initial value (ANCOVA of arcsine transformed percentages, with body mass as covariate, followed by Newman-Keuls test; =0.05). See Table 1 for sample sizes. Sample sizes of control groups were 13, 8, 10 and 9 for B. judaicus, L. quinquestriatus, S. m. fuscus and S. m. palmatus, respectively.

Family-pooled data (mean ± S.E.M.) of total body and hepatopancreatic water contents (percent of body and hepatopancreas fresh masses, respectively), following losses of 0, 5, 10, 15 and 20% of initial mass. Sample sizes are as in Fig. 2 (pooled within families).
