What is this?

We found this on a piece of live rock this morning. I added some snails and hermit crabs yesterday. The second picture was taken after one of the crabs turned it over.

Looks like a hermit crab out of its shell . If it’s not moving it’s probably a dead hermit crab out of its shell . And WELCOME!!!

That’s what I thought it looked like, but all of my crabs are still in their shells and alive.

lol! I thought I lost my emerald crab the first time it molted because the skeleton was so perfect. I checked inside and was relieved to find it hollow.
