Invert ID

[Marineman]

Can someone ID this creature for me, it comes out only at hight, it's 2 .5" in diameter, the center line (mouth) is white in colour if it opens up.

Some marine mollusc. Probably a nudibranch or flatworm of some sort.

Yup, at a glance looks like a mushroom except that it moves and it's mouth is elongated.

Nudibranch or flatworm (a big one that is!), I am also not sure myself, anybody can be more specific?

It's is the same one (I think) I saw in RC TOTM under Inverts section
