Picture is a bit fuzzy, but looks like a pineapple sponge. Suggest Googling "Pineapple Sponge" to see if that is what you have.

Feel like I see a tube and a tuft so thinking vermetid snail. Blurry pic. Hard to tell.

Sorry for the blurry picture, it looks like an anemone that has closed up. Its smooth on the outside so its not the pineapple. It is only about an 1/8" tall so its hard to see on a picture, I'll try to get a better one posted. Thanks.
