By either grabbing onto something thats close or digging a hole and hiding in it :3 (thats my best guess which i believe is right)
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?).
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.
crabs live in the high zone and in the splash zone
Land hermit crabs don't, they put them on damp sand at low tide, when the tide rises it carries the eggs away.
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.
Of course they do! Unless the crab is dead.
The rocky shore is a place on the rocky parts of a beach w/ animls. They experience middle tide, low tide, high tide depends on moon. this makes crabs and cucumbers and seagulls and fishes live in harmony There are also horeshoe crabs.
In the summer
Crabs tend to live close to beaches and during low tide they come out to play :)
The intertidal zone is the area on the shore between the highest tide mark, and the lowest the tide gets, in that location. Many small crabs, such as hermit crabs, inhabit the intertidal zone.
limpets can die when the tide goes out as the waters not around them.
you cant, the high tide comes in then the low tide comes
