Alien in my reef tank

[ReefMang]

Lets see who can figure out what this is.... I kind of freaked out a little when I saw this today. Had my son shine a flashlight into a hole in my live rock to get a better pic. I noticed it when I saw something come out of the darkness, grab a piece of clam and then scurry back into the rock to feast.

I think I saw a larger version of that in the movie "Monster Trucks".

I'm going with it's a type of Ophiuroid, a serpent star, and the two holes you are seeing are fully opened exhalent bursal slits.

How long has he been in there and you didn't know it?

Congrats Chowwil was the first one to get it. The pic is of a serpent star. In the pic it definitely looks like an alien though!

I had no idea some of them had vents like that. Looks very octopus like. Don't worry OP, I'm sure you have a solid lid and you won't wake up to it implanting eggs in your mouth.
