Who's that in the hole in the mud of the salt marsh in Wellfleet Mass?

Why it's the Atlantic salt marsh fiddler crab! (Scientific name: Uca pugnax) These adorable little scavengers were very abundant when my dad and I went walking by the shore on our recent visit to Cape Cod. Sexual selection by the female crabs has driven the evolution of one oversized claw on the males.
