Atlantic Ghost Crab

Ocypode quadrata


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.
