Calico Box Crab
If you go diving in the western Atlantic Ocean from the Chesapeake Bay to the Dominican Republic, you may run into this gorgeous crab, the Calico Box Crab, Hepatus epheliticus. It lives in shallow water at depths of up to 46 metres (151 ft) on sandy and muddy substrates. It often carries the sea anemone Calliactis tricolor on its back, or lies buried in the sand, with only its eyes exposed.
