Absolutely. Everything that breathes air has lungs.
As most people know hermit crabs have gills most animals that breathe under water have gills for example a fish. The hermit crabs gill's can work on land but in order for the hermit crab to survive they hermit crabs gills have to be moist....
no crabs dont have gills
Yes.
THROUGH GILLS
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.
No, crabs are "invertebrate" animals, they do not have a backbone.
Hermit crabs use gills to breath.
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
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.
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.
Hermit crabs will suffocate in an environment that has too little humidity because they breath through modified gills.
