I call myself Nature Girl because I love being outside around nature. I was walking along the shore at Grape Bay at low tide with my Grandad when we spotted these shells. We watched the Bleeding Tooth shells moving slowly up the rocks as the tide was coming in. They were leaving trails in the sand that looked like a path for the others to follow. If you turn one over you will understand how the shells get their name. Just be sure to return the shell exactly where you found it.
