I have an animal that seems to have crawled out of some new live rock. It looks like a black snail with little white dots all over the body and shell, but the shell is flat, like someone ran over it with a car tire. It's about 3/4"-1" long. At first I thought it was a slug. It's cool looking, but I was just wondering if anyone knows what it is. Sorry, I don't have a camera. Thanks in advance!
