Why are crabs sold alive?

In short, we cook lobsters alive to minimize getting sick from them.

Can crabs live out of water?

Some crabs swim. … However, unlike fish, blue crabs can survive out of water for long periods of time-even over 24 hours-as long as their gills are kept moist. When out of water, crabs will seek out dark, cool, moist places to help prevent their gills from drying out and to hide from predators.
