hitchhiker

Hey folks- its time for another exciting episode of "Name that Starfish" Everyone's favorite show. It looks similar to one on Chucks addiction but can't tell. And the next question if you can name him....is he reef safe?

I was moving somethings around today and noticed a few things I didn't before but not sure what they are. If anyone can help ID I'd be greatful. this one I just notice it is white in color this next one I've seen for a few months, it started as a small spot on a rock now it has covered...
