I believe there are published records of island populations of Vipera berus in the Baltic Sea (brackish) in Sweden that regularly "commute" between islands (documented by mark-recapture) - separated by only a few 100 metres, but sea-going nonetheless. I don't have the references at hand, but let me know if youy are intrested, and I will try to dig them out.
Cheers,
