Description Ocypode quadrata is a species of ghost crab, once described as an "occult, secretive alien from the ancient depths of the sea". It is a common species along the Atlantic coast of the United States, where it is the only species of ghost crab; its range of distribution extends from its northernmost reach on Rhode Island's beaches south along the coasts of the tropical Western Atlantic Ocean to the beach of Barra do Chui, in Rio Grande do Sul in Southern Brazil.

Adults are greyish or the colour of straw, and approximately 5 centimetres (2 in) wide at maturity. They must return to water periodically in order to moisten their gills, and when larvae must be released into the sea, but are otherwise terrestrial. Their stalked compound eyes can swivel to give them 360° vision. Young crabs are cryptically coloured to blend in with their sandy habitat.


Habitat Sandy beaches.


Range Texas, New England, Mid-Atlantic, Florida.
