Does anything eat a shrimp's molted exoskeleton?

[hopperjl16]

This morning I noticed my fire shrimp had molted overnight. I had intended to pull the exoskeleton out when I got home tonight, but now it's nowhere to be found. Is there anything that eats exoskeletons? The only things in my tank that I think would be remotely interested are hermit crabs, emerald crab, pistol shrimp, or brittle sea star. Will any of these demolish an exoskeleton?

We watched a nassarius snail graze on the molted exoskeleton but parts are still on the sand bed...

Hmmm....I do have 2 nassarius snails....

No need to give it a second thought, the exoskeleton breaks down.

Our Blood shrimp molted again and the remains stayed in the tank for about 24 hours then, once again, were gone... I kept an eye out for CUC at work etc, but didn't see anything during the day. I'm assuming something scavenged it at night.
