I am entertained by the antics and abilities of Ghost Crabs when I visit the beaches they inhabit. They are constantly excavating burrows in the sand, defending their territory against competitors, and hunting down with impressive accuracy the insects that gather on the sand and seaweed. No creature on earth can out run the sands of time, however, and this crab shell appears as if it was in mid-reach when his time came. This image captures the gritty struggle for life in the intertidal zone.
