Adult Menippe mercenaria generally inhabit sub-tidal regions; they burrow under emergent hard substrate or in seagrass beds. Juvenile stone crabs are found nearshore in marine waters on seagrass beds, or around emergent live rocks in highly dense populations. Some juveniles have been caught in deep channels near the Florida coast. The stone crab larvae travel with the zooplankton, upon which they feed, in nearshore marine environments.
