    Almost looks like a thorny oyster. Interesting, you do not see those everyday. I like bivalves. Do not hold me to that ID because it is hard to tell from the pic.

    It could be a jewelbox mollusk (bivalve) too. It's going to have to grow to know for sure. (It doesn't really matter.....both are harmless)

    No most oysters or mussels usually attach via byssal threads. And some are rock boring. You would not see the kind of foot you would see with Tridacna.

    Depends. Some species hold on with a foot, some hold on with byssal threads and pull their foot inside.

    Is it soft or hard? if its hard I agree with the posts above, if its soft its probably a rock anemone -- anything I have learned from this site is that pictures can be misleading.

    They've already narrowed it down for you, and it's either a Spiny Oyster (Spondylus) or a Jewel Box (Chama species). Some of them can look very similar, and yours is one of the oysters with intermediate characters. It may already be dead if you aren't seeing the mantle. Harmless in any case.

    Cheers,
