Jesus sleeps with the fishes?
That's the whackiest looking fish carving I have ever seen. I don't see a human form in its mouth. To me it looks more like a chestnut or walnut or scrotum. I'm not so sure it's a fish. When I first glanced at it before I read that it was a fish, I thought it might be a person (poorly carved of course) without shoulders and a really poor fitting dress of dubious design. The fact that a team of "archiologists" was lead by a film maker is the first fly in the ointment. I'm reminded of those shows about monsters and UFOs on the history channel, which always end with the same line about lab reports "Results are inconclusive".
