As the name suggests, these crabs are foundmostly under the water. If they stay outside water for a long time,the moisture stored in the gills is lost resulting in collapsing ofthe gills. The intertidal crabs can breathe easily both inwater as well as on land. When in water, the gills help inrespiration..

As long as their gills stay moist, these crabscan spend their lives out of the water. But if they weresubmerged in water, they would die.
