Sipper lobster shell shed.

With all crabs, lobsters and shrimp, the front part called the carapace opens up between it and the tail and out squeezes the new creature to swell filling with water while its new skin becomes a shell so its bigger with each shed.
Though you can not take slippers any more, its still cool to see them and this case, an empty one.
First up a slipper laying there?


Then of course its an empty shell, with heaps of barnacles on it that if left to long, it would not be able to fit into tight spaces to hide, then death.


The shell now squashed, no slipper in there, lol
