I think cucumaria is a safe guess at the genus. Beyond that, I couldn't tell you.
Wouldn't rule out a medusa worm as my second guess.

Hard to tell from the picture and most likely my guess is wrong but looks like a small black cucumber (some have a more grayish color).

I'm officially going with Medusa Worm! I searched and searched and didn't come up with that at all. Thank you for the guess!
