Is it or is it not a snail?

I got a couple of nice zoo frags at the LFS and got a hitchhiker with them.
Anybody know this critter...(excuse my non-drawing abilities but the darn thing is so small, 1/4" or so, that I had to draw it 'cause pics were not coming out, I will try to get a pic if I can find it again.) From the top it kinda' looks like a pillbug. Seems to be content roaming around the rocks eating detritus and algae...the shell part is definitely soft and pliable!!

 

amphipod? Does it look like a crustacean? Does it have legs?

 

What is the whitish-yellowish stuff? Is this part of the critter?

 

Maybe a limpit
Maybe a chiton
hard to tell. The pill bug body makes it sound like a small chiton to me.

Great drawing BTW, I like it

 

hmm i have heard of zoo eating snails bit they look more like snails than that...maybe a uh...stumped

 

Its a type of seal slug (nice drawing, easy id) it is either a close relative of the reticulated sea slug (Oxynoe antillarum) or is one. This particular genus feeds specifically on clpra algaes (almost always grape type). If your give it grape algae it can reproduce prolifically, but if you have some and like it you better loose the critter. Birdlady just found a similar one on her algae. I would bet the keep there macro algae in the same tank as the zoos....of pump water in from a fuge, or it was kept with that type of algae at one time, or that typ of algae was kept in the same area as the zoos at one time and the slug transfered to the zoo....sorry i just feel like ranting... k im done

 

just guessing... a pic would be better for ID but.... Heres a thread i started :Snail ID

Looks like a stomatella to me.  Here's a link to some really great snail pics

Thanks gang...great responses and links. Caulerpa is illegal out here in California so that is not a problem. I can't get it anyway. And yes fishy that is the snail part of its body, the part that oozes over the rock. I will follow up and let you know. Hopefully it will present itself for a pic!!!

http://images.google.com/images?q=Oxynoe antillarum&hl=en&btnG=Google Search....if your pic os proportional its not a stomatella......the foot is too exaggerated to be one, the shell (if the pic is an acuurate one) is not nearly correct proportionally.....check the site, they are highly variable in color and texture and only a few species are described but the genus is unmistakable.
