I'm hoping that someone can help me ID this creature that just popped out of my live rock. It's a little smaller than a dime, sort of turtle shaped, with a nose/mouth/snout very similar to a conch. I saw it, ran to get my camera, snapped a couple of pics, and then it was gone. It could see it in a hole in the rock for a while, but when I came back later it was gone. Sorry for the bad picture, but it was the best I could do!
If anyone knows what this is, please let me know. Should I remove it (if I see it again)?
Thanks!
