yes because I have crabs right now in fresh water and they are still living.
Yes
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.
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?).
no , crabs live in fresh water
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.

First of all, sand crabs are not hermit crabs. Sand crabs are usually tan, white, brownish, or other flesh-like colors. If you catch one, let it go--They need water.
Mudskippers, crabs, and amphibians can breathe under and out of water.
a lot because they get the water from the sand so just go to a mudflat thing and get a handful of waterlogged sand

Sand crabs are a very small type of crab. They mostly eat plankton and other organisms they filter out of the water.
no
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.
