Can blue land crabs breathe underwater?

Can a crab breathe underwater?
Breathing free and easy. Crabs, like many sea-dwelling creatures, have gills that they use to extract oxygen from the water in order to breathe.
Will crabs drown in water?

How do crabs breathe in and out of the water?
They are abundantly found on tropical seashores where some have adapted to terrestrial life. Though they can live on both land and water, they are not amphibians.
