Black Slug Critter ID

[thefishgirl]

Hi Guys...

So I picked up my tile of mushrooms today to flip it over as I wanted to see how they were splitting. It's been splitting a lot recently. Imagine my surprise when this thing crawled across my finger. I just about died. LOL It's black with feelers and looks like a slug/snail body.

Any ideas?

I have these in my frag tank as well. I always thought that they are a soft sided snail. They don't seem to like light too much and move fast when they are in the light. If someone else has a ID on them better than that I would like to know as well.

cant recall the name off the top of my head....but its a good guy. No worries. Its got a slit on its back- when it opens slightly you can see its white shell underneath. Wish I could remeber the name....

By the looks of it, you would think its poison/gonna sting- but they are harmeless.

Yes.. I was shocked at how quickly it moved. Scared the **** outta me! I dropped my tile in the tank. My goby just stared at me as if I was crazy.

Hmm... so...if I actually touched it's back, I could feel a hard shell under it's slimy exterior? Lemme find my gloves.


Stomatella

Thank you Bongo. You truly are the King of ID! :)

I vote limpet. Very possible on the stomatella though. Just depends on the white internal shell w/ the flaps, vs. a small visible (possibly camoflaged) shell on its back.

Sorry sir but I know I'm right on this one, it's a black stomatella. Scutus can't move as fast as described anyways. :)

[Sir Patrick]

^ no worries- just tossin it out there. :)

It looked A LOT like that link that Sir just posted. But he was very fast. I'll see if I can get a better picture. Either way..it appears to be reef safe except when encountered by the screaming chick that drops stuff in the tank. *look out below*

i had the same thing in my tank but the white version. i didnt know what it was so i fed it to my mantis shrimp but after further research it was stomatella

I'm on the fence with this one... I'm leaning towards Scutus but Bongo's confidence in his Stomatella ID has me wavering. I should also say that my opinion is based on books (photos and descriptions) and Google images solely, as I've never seen a live Scutus or "black" Stomatella (plenty of gray S. varia though).

You may want to get a definite ID on this one as the description in "Invertebrates: A quick reference guide" by Sprung states the Scutus eat coral tissue and are not reef safe. I'd post this photo (and/or clearer ones) in Marine Depot's Invertebrate forum where Dr. Shimek could throw in his 0.03 cents. And please let us know what he says!
