Can you guess what this is?

Last night I found one of my Zebra Tubro's had passed on (May he rest in peace) Well, while I was checking him out, what I thought was part of the snail began to move once the lights were on it.

It made it way slowly back into my rockwork only to return again to feast on the snail when I decided I would try and catch it. I was ultimately unsucessful, but got a pretty good look at it.

It moves like a snail and is about as fast as my Tongan Nassarius'. It is a brown mottled color and is totally flat from what I could see. It does not seem to have any head, eyes or appendages of any type. Size wise, I would say it was close to 2 inches long and about a 1/2" wide.

Sorry for the bad pictures. It's the brown thing draped over the top opening of the snail shell. Anybody want to take a stab at what it is?

Sea Slug (Aplysia californica)?

Does it look like this?

It's definately the same color, but I didn't see any eye stalks on it (or eyes for that matter) and it was totally flat when moving in the sand. It didn't have the same clindrical body structure as a sea hare from what I could tell.

When I frightened it with my light, it sucked itself into a hole in my rock about the size of a dime. Kind of like an octopus would do. Plus, it looked to be sucking on my snail like it was a snacky cake. I looked up the scientific name that you gave me, and it says that sea hares are herbiverous algae eaters.

I gonna have to go Jacques Cousteau on him pretty soon if I can't figure out what it is. I don't want to move something potentially bad to my new setup.

Looks like a type of polyclad flatworm. I couldn't even begin to guess on the genus. I'll see if Boomer can pop in here...

Yes Nikki, I agree a polyclad. I'll see if I can find an image for you guys of it.

Oh boy! As ornate as some of those specimens shown are I'd have a hard time believeing that they would be classified as "Reef Safe" due to the law of nature [bright colors = "Im poisonous"].

I guess if it isnt actively killing snails or eating corals then is isn't causing harm. That you know of.
