As long as their gills stay moist, these crabs can spend their lives out of the water. But if they were submerged in water, they would die. Other crabs, like blue crabs, are primarily aquatic and are adapted to receiving their oxygen from the surrounding water. Yet, they can still survive for 1-2 days out of the water.

What happens to crabs in cold water?

Can blue crabs survive in freshwater?
Blue crabs can live in fresh water, but the females need to migrate to the ocean to release their eggs into salt water. So your choice of environment would be subpar in getting crabs to breed and release eggs.
Why do crabs bury themselves in the sand?
