Stumbling along a beach in Okinawa is different from the same activity on those beaches I have stumbled along hitherto.  Okinawan beaches are bustling with hermit crabs. There are thousands of them. Where do they find their shells? There are no empty ones. Every shell is already occupied. It is a seller’s market when it comes to housing for crabs. I fear social disorder amongst homeless crabs.
