Of course they do! Unless the crab is dead.
There are crabs which breathe water and crabs which breathe air. It is rare to find a crab that does both but intertidal crabs do but they must remain wet to breath air (strange, right?).
Sand crabs breathe through gills, in the same way that fish do. On land, sand crabs breathe by keeping their gills moist to facilitate the absorption of oxygen in the air.
Crabs have gills. They breathe by letting water run over their gills and getting the oxygen out of it. Crabs that spend some time on land carry a little water inside their shell so they can still breathe. This is why you see them running in and out of the water at the seashore.
yes because I have crabs right now in fresh water and they are still living.
Crabs have gills. The underwater ones have larger gills than the terrestrial ones. Terrestrial crabs use the humidity in the air to breathe. this is why crabs live near water even if they are land dwellers. some crabs have very small and basic lungs but these cannot function without water and are usually attached to some sort of gill.
They are related to lobsters, shrimp, and crabs. They have gills, and need a moist environment/habitat to live in.
i think they breathe by lungs. zydarius Daniels age 10 Wayne avenue school class miss e
Mudskippers, crabs, and amphibians can breathe under and out of water.
Arachnids such as spiders and scorpions, and crustaceans such as lobsters and crabs.
The animals that breathe through gill chambers are crabs and mudskippers. Their gill chambers also function in the storage of water.
Marine crabs breathe underwater using gills, which are located in a two cavities under the carapace. True land crabs have enlarged, modified cavities that act like lungs so that the land crabs can breathe air
Land hermit crabs can't breath out of water, they will drown, they have modified gills, which means they need humidity to survive. (70-85%).
