Actually the shark teeth thing is just part of the 'handle' of the item which is made from clay. i'll send marty a better picture of the whole thing. There were two different vendors selling these things and the dagger part were all around the same size. the crack in it (where it's attached to the handle by the shark teeth) appears that it's hollow inside...and almost looks woody. I seriously doubt that it IS wood because of the detail of the little bumps sticking out of it and the fact that the bumps that are missing are a perfect hole that are empty inside. This was purchased on the beach so i have assumed it was an ocean creature. It just doesn't look sharp enough at the end to be any kind of weapon or something to pierce with...that's why I'm baffled. It doesn't even look like a nose of anything, much less a tail (although that would be more logical). The thing I saw on River Monsters that he was holding up was REALLY long...like at least 3'...IF it was even the same thing but it sure looked like it.
