Populations of Rhizophora mangle (salt-excluding) and Laguncularia racemosa (salt-secreting) in the Maracaibo strait in Venezuela showed: 1) significantly larger succulence in adult leaves of Laguncularia; 2) higher concentrations of N, K, and Mg in Rhizophora and higher P, Na, Ca, and S in Laguncularia; 3) both species resorbed C, N, P and K and accumulated S, Na, Mg, Ca, Mn, and Fe. Compared to Laguncularia, Rhizophora restricted Na and S uptake, resorbed more P, and accumulated Fe.

Short summary
Dice snakes live in freshwater but are able to spend prolonged periods in sea water for food foraging. However, it is unclear whether foraging in salty sea water has a physiological cost. Our experimental data suggest that even though dice snakes show a remarkable tolerance to waters with increased salinity, prolonged exposure induces significant physiological stress (increased metabolism, membrane rupture), which should limit their ability to stay in them for long periods of time.
