Crabs Cited in Salt Marsh Decline

This shows a large male purple marsh crab (Sesarma reticulatum) clipping cordgrass with its claws. The burrow opening in the photograph leads to a large, communal burrow inhabited by 10-15 crabs. These crabs are nocturnal and typically reside in burrows during the day to stay moist and avoid predators. Photo credit: Tyler Coverdale
