I was recently in Myrtle Beach, SC and while walking the beach found a couple of sand crab friends. Below is a picture of one who was fighting with the rising tide and holding its own place.
Cool idea but.. I can't really see the crab very well... I think it needs a bit of a tighter crop. I would have also possibly gotten closer to the ground so you can see more of its face. But who knows.. maybe you would have been a little like me and not want to get toooo close to those claws...
