An issue of maritime law

So working on a review for this week for a film that I saw yesterday, and I have this question .... Suppose your wife is, say, swallowed by a whale. But she's still alive in the whale's stomach. Technically speaking, are you still married? And if you marry someone else, wouldn't it be bigamy? I've gotta think so. Til death do us part and all. Is there a lawyer around that can speak to this?
