Crabs gills are special they have a part that can help them take the oxigen without needing water.
It has gill chambers to store water so that they can breathe using dissolved oxygen from the water while on land.
They have gills under their mouths that allow them to breathe. When the gills start to dry out, foam forms at the mouth, telling you that the crab has trouble breathing.
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
-Because they can find foods on land... & they are not live on water.. they live on seashore so they can drink & find foods....
They use lungs and gills.
Crabs need oxygen, just like we do, but instead of using lungs inside the body they use gills outside the body to obtain it.The mouthparts are visible on the underside of a crab. The gills through which the animal obtains oxygen cannot be seen. They are soft structures under the side of the shell.Their shells help to trap water near their gills so that they can still breathe the oxygen .
Of course they do! Unless the crab is dead.
crab
yes.
Yes, they breathe to extract oxygen from the water like a fish.
so when the eggs hatch the baby hermit crabs know where to get the water so they can have it in their shells to breathe.
