Helen With AShell
I believe this is a Tiger cowrie. I found it on the bottom wedged between two rocks. It was wedged in so well I had to use both hands to pull it out. Once we got to the surface we figured out it was still live (something in the shell) so it went back in the ocean. Another couple pulled up another example and it was much heavier for the same size - I think our example was slowly starving.
