HELP, What is this? Not a fish....

See The hole on the far right of it? (looks like a square) If u get close to it, it will close (The whole thing will shrink) It weighs almost nothing and is about 4-5 inches long.
I got this at my pet store today with some live rock but they didn't say anything about what it is.

Look up sea apple.....I'm not 100%, BUT I think that may be what you have
I also believe they are poisonous if they die

Why would you but an unknown object??

WE THOUGHT IT WAS A ROCK. PLACED IN BAG.(WITH OTHER ROCK) BROUGHT HOME. PUT IN TANK. SUPRIZE

Seascape! That's my LFS! Awesome place, but can be pricey.
