The larger hermit crabs have been known to submerge their entire bodies into the sea water. The saltwater is used to bind the shell to the crabs back through the high salinity in the water. [6] In addition, water in the shell allows for rehydration, wetting the surface of their gills and abdomen which aids in gas exchange, reducing their body ...
