Slug, worm or what?

[brewman1987]

So what I thought was a yellow sponge is now obviously some creature. It moved to the sand bed and is quite interesting. It is probably about close to 2" in length. Any ideas what?

the picture is really blurry but I would guess a sea hare of some sort. Can you take a clearer picture?

It's a nudibranch, and looks like a Platydoris species. As far as I know they are sponge eaters.

I will try to take a better pic.

It's definitely a dorid nudibranch. I'm just not positive on the species-level ID.

It might be far fetched but ....Do you know wether it came from a rock or a coral/ sponge you bought recently ? Perhaps knowing the origin country of the live rock or coral might help identify the nudibranch.

It was part 1 package from Tampa bay SW so Gulf of Mexico.
