What in tarnations is this guy?

[holloway]

Any idea what this little guy is? He's about the size of a quarter. He looks like a black mushroom but he has antenae and moves like a snail. He was hiding under a piece of fox coral. I quarantined him and the coral (I couldn't get him off). Anyone know his name or personality. Is it reef friendly? Thanks.

Some type of sea slug maybe? I'd rule out a sea apple since I just got one on some zoos I just got. The members here helped me ID it so I'm sure someone will give you the right ID.
Here's a pic of the sea apple to compare with yours...

it looks like a black flat worm but im not sure on that so see what other opinions come along

I think it is a Scutus - a type of snail but also known as an Elephant Slug see the attached link

FDA483 you rule. That's exactly what it is. In fact after reading the link I think I've solved the mystery of the "tiny albino snails" ( the Scutus babies) that race for cover when the lights come on. Great job. Thank you, Thank you. He's going back in the tank.
