How Do Crabs Breathe? - Boxhill Crabcakes


How Do Crabs Breathe?

Crabs, like many sea-dwelling creatures, have gills that they use to extract oxygen from the water in order to breathe. But you’ve probably seen plenty of crabs on land too. So how does a gilled creature breathe on land? Surprisingly, all they have to do is keep their gills moist. This allows oxygen in the air to diffuse into the moisture and into the gills, allowing the crab to breathe. All it has to do is take a quick dip in the surf to keep its gills wet, and a crab can crawl around to its heart’s content on shore. Their gills are also surrounded by articulating plates that seal them in and prevent them from drying out. If they want to venture further away from the surf, crabs also like to find cool, dark, moist hiding places that hide them from predators and keep them breathing.


Land crabs are even better than blue crabs at breathing on shore. They can drink water from the dew and ground, extract it from food, and from water vapor in the air. They store water in the bladder, blood, and various pockets in their bodies to use to keep their gills moist for extended periods of time.
