How long exactly can a crab live out of water? That depends on a few factors, such as the type of crab and the temperature of its surroundings. For example, hermit crabs can live for up to two weeks out of the water if their bodies are kept moist and they’re in a cool environment (below 70 degrees Fahrenheit).

Conversely, blue crabs will only survive for about 24 hours when removed from their aquatic homes. So why is it that some crabs can go longer without water than others? It has to do with how much oxygen their bodies can store.

Hermit crabs have gills that help them absorb oxygen from the air, while blue crabs rely on special cells in their blood (called hemocyanin) to transport oxygen throughout their bodies. These cells are less efficient at doing so when they’re not submerged in water, which is why blue crabs don’t last as long out of H2O. Of course, just because a crab can technically survive outside of water doesn’t mean that it’s good for them to do so.

If you must remove a crab from its natural habitat, be sure to keep it moist and in a cool place until you can return it to its rightful home.
