Do you think that the blue crab can survive out of water?

Yes, but not for a long period of time

Explanation:

-> My answer comes from some quick research I did

        "Blue Crabs can last up to 24 hours out of the water as long as they are kept cool and moist." (crabbinghub.com)

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
