Can crabs live out of water?
Yes, some species of crabs can live out of water. Terrestrial crabs, which have often evolved from freshwater crabs, can be found in a wide range of water bodies, from fast-flowing rivers to swamps, as well as in tree boles or caves Some species of freshwater crabs are also able to tolerate freshwater conditions or are secondarily adapted to fresh water Hermit crabs, which can be divided into two groups, the aquatic hermit crabs and the land hermit crabs, can survive briefly out of water as long as their gills remain moist Golden ghost crabs are semi-terrestrial and breathe oxygen from the air through moistened gills. They must periodically wet their gills with seawater, usually by taking water from moist sand or burrows.
