What is this thing?

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?

weird looking thing... maybe it is some type of jellyfish? that would be my guess since all the others that washed up.
