My family is on vacation at the beach, just outside of St. Petersburg, Fl. While walking on the beach this afternoon I found this laying at the edge of the surf. It's about 3" long and solid (took some serious pushing to cut through with a plastic butter knife). There are quite a few of them on the beach. Most are gray, but this is the only one that I found with color still in it. There is no skeleton.
So anyone have an idea what this is?
