What is this?


Recommended Posts

I have got a pretty interesting hitchhiker on live rock bought a few days back.  It opens and closes, but not like a clam, more like a scissors.  I don’t see a shell, just a woven type of skin..  It does shift its whole self up and down very little. And does shy away by clamping shut.  It’s about the size of a dime.  When it opens, a microscopic tongue that resembles a worm comes out and feels around.  Picture are of mouth open and one of it closed.  


Thank you in advance!

Where did you find that picture?  Although yours looks similar, I did a search on Barnacles, but am not finding anything pointing to these being in the Barnacle family.  Can you find out more information, Christy.
