Ghost Crab Ocypode quadrata
Ghost crabs can be found on the upper beach and dunes around most of Florida. Adults have square yellow or white bodies while juveniles are mottled. Ghost crabs feed on small animals in the swash zone and any detritus washed up along the shore. These animals construct burrows in the sand, sometimes forming complex tunnel systems. Normally these animals reside in their burrows during the day and are active from dusk till dawn. Numerous burrows are correlated with healthy beaches.
