The nocturnal ghost crab (Ocypode quadrata) stands erect on the tips of its legs; hence it is amazingly quick and agile. This beach dwelling crab is almost white in color and reaches lengths up to 5". It has strong claws for crushing small clams and mole crabs upon which it feeds. It lives in burrows under the sand during the day in order to keep its gills moist. Ghost crab burrows typically have multiple tunnel entrances, which are easily spotted along the dunes of Key Island.
