strange snail

[Tackett]

hey, I have found a strange snail, he has been in for some time now and appears to be a herbivore, he hasnt bothered any of my corals and I have seen him chowing on some algae sheets I place in the tank for my yellow tang. Just cant figure out what he is. I dont have a pic yet (sorry) but will try to get one. He is small (about 1/2 to 3/4") his shell is a dark dark green almost black color. He doesnt look like a normal snail, His shell is oval and elongate like a baseball cap without the bill. He has a few barnacles on his shell. I have tried to pry him from a rock to take a look at him but I cant get him off of what he is stuck to. He feels almost like he is superglued and since he hasnt hurt anything I dont want to hurt him. Like I say, I will try to get a picture of him soon. Any Ideas?

nope that aint it. you cant see the soft part at all it is completely hidden by the shell.

keyhole limpet

possibly some type of limpet, but I dont think it is a keyhole species because it has no hole.
