Tiny Crab Claw.

I found this dead crab today, not the smallest crab I've seen but still pretty small.

Funny thing was I found it on an internal staircase, and no-where near any of the animal feeding areas. So I have no idea how it got there.

When I picked it up, it disintegrated, so had obviously been there awhile. The staircase isn't used by many people and is quite dark, so that's probably why it hasn't been found before.

This claw didn't fall apart, but it was a bit smelly!
