The pelarmis are an open ocean snake that live on the surface. They can go backwards just as good as forwards and this is their sneak tactic to catch fish. The storms bring them in and whether they do any good when released back at beach side is beyond me. Usually they suffer from injury, from being bashed while beached, and this is generally their demise.
They can be kept quite all right in fresh water (tub or bath)for short periods, as long as there is some plastic plants to put in there for it to hide amongst. I took one down to a fella at Darling harbour marine world once, who was giving them a go off display. It was relatively uninjured and survived the trip down from Woy Woy to Sydney on a train in a small tub with wet paper towels and rags in a back pack, quite well. They are a very nice looking animal, with some really cool traits, and are venomous, i know of a vet that was tagged but he suffered nothing and released himself from hossy.
