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.
