What the heck is this?

Recommended Posts

It came as a hitchhiker on live rock. If I prod it, it moves and the visible hole closes. It is not part of the rock. pic1 is from what appears to be behind, pic2 is from top side.

Some sort of bivalve. Harmless filterfeeder


Nice sponges BTW. Are they hitchhikers or did you buy them?

Ordered the package from Tampa Bay Saltwater and the sponge in was included. I would recommend TBS as they included some amazing animals and have always been very quick in responding to questions.
