The development of tadpoles under salty water. The difference of developmental stage before and after salinity acclimation of Duttaphrynus melanostictus (left), Fejervarya limnocharis (middle), and Microhyla fissipes (right) tadpoles in freshwater (open square), low salinity (open circle), and high salinity treatments (x-mark). Values of Δ stage with different letters represent a statistical difference (Kruskal–Wallis tests with Dunn posterior tests, p < 0.05) among treatments. Duttaphrynus melanostictus: n = 12, 12, and 7, respectively; Fejervarya limnocharis: n = 12, 12, and 8, respectively; Microhyla fissipes: n = 10, 10, and 7, respectively. Data presented as means ± SD.
