Tentacled snakes are fully aquatic, but pretty difficult to care for from what I've read online and in books about them. Apparently you need to keep the salinity at a brackish level to keep blisters from forming, but they need fresh water to drink. In the wild, they drink when it rains and since salt water is heavier than fresh, they'll drink from the layer of fresh water that forms on the surface during a good rain before it all mixes together again. Gnarly. So, as much as these snakes fascinate me, how the heck do you simulate THAT in captivity?!
