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 .
