Something on Zoa (ID Please)

[Myka]

Might be a Zoa Spider. Tough to say from the pic. Take it out and dip it. See what comes off.

The circle on the bottom, that doesn't move, does it? Looks like the tube of a Vermetid Worm.

I agree with Myka, dip it. At the very least whatever comes off can have a closeup photo taken and a better identification. I'm always interested in hitchhikers that I haven't saw before.
