Body fluid [Na ⁺ ] values of the three sea snakes subjected to freshwater (FW) and seawater (SW) acclimation. The body fluid [Na⁺] values of (A) L. semifasciata, (B) L. laticaudata, and (C) L. colubrina. Each value represents the mean ± SEM. Values with different lowercase letters significantly differ (p < 0.05, Tukey's HSD).
