What is this invert?

So I took out a piece of my Live Rock to pick some algae off it, and this thing fell out. What could it be?

looks like some sort of slug....or sea cucumber?

The darker part you see up front is a shell, but it doesn't look like any of the snails I have in the tank...

I forget the name of this hitchhiker, but they arent anything to worry about. They are a type of snail with a half shell of sorts. They will breed in your tank and mow down algae.

Looks like a flatworm.

It could be a Chiton... Maybe a Stomatella Varia... both are harmless btw... http://www.chucksaddiction.com/Hitchsnails.html

Thats what I was looking for, Stomatella.

Chitons have segmented shells that are centered on their body.

Thrse snails are awesome and faster than any other snail ive seen... Great inverts, and they love algae.

Not all Chitons have segmented shells some don't even have a visible shell, and look like flat slugs, and some only have a little shell. There is alot of veriation.
