what the heck is this thing?

Found this thing in my rocks. It used to be closed up and I wasn’t sure if it was alive. Today I found it opened up like this.

Any thoughts on what it could be?

Looks like a BTA in REALLY bad shape…

Really, you think it could be an anemone? That rock was once in with a BTA, but hasn’t been for a while now. I’m not missing any BTAs either

Maybe it’s a split of the one(s) you had?

It looks dangerous, send in the eel. Remember the first Alien movie and that egg.
