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 breathe through their skins
earthworm
Crabs outgrow and then shed their skins
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.

Frogs use their moist skin to breathe when they are in water😊
The animals that breathe through gill chambers are crabs and mudskippers. Their gill chambers also function in the storage of water.
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?).
they just breathe, you don't really Noe and if u don't Noe ask a scientist lol

I'm not too sure if they breathe through their lungs but I'm very sure they do breathe through their skin. Frogs and toads' skins are rather thin for oxygen in the air to pass through and also to get rid of carbon dioxide unlike other mammals or fishes.
Yes, its very healthy for them.
