How to safely get a porcelain crab out of a rock

[tlhood]

I certainly can try, I will take a picture when the lights turn on again. There is a whole clump of legs sticking out of one cave right now, but they aren't stretched as far as they can go. I'll post a picture later this afternoon. Some of them are white with black knobs, and some of them are red with faint black knobs. I assume its a starfish by the way it extends, grabs on to something (usually Mysis) and then pulls it back towards the cave. It could be some creepy mutant sea monster, all I've ever seen are 'legs'.

And my Crab-trap jar is in the way right now, though my porcelain crab seems uninterested in the goodies in it.
