not long. they need food, a warm and humid climate, and water
As long as your mother can keep in the freezer, she has the crabs ask her where they are.

It keeps it fresh long.
Yes you can freeze it. Freezing virtually stops the aging process of food. It can be store twice as long as it stays fresh in the fridge. Try it out, it works.
Only a day or so, unless it is frozen.
8 months if stored properly.
. . . not if you want them to survive. Salt-water crabs require at least brackish waters.
It depends on whether it is fresh(self caught) or non fresh (frozen) I believe frozen fish will last several months and will be in pristine condition until at least 6 months in the freezer. As for the fresh fish I would recommend you consume this within 2-4weeks.
Meats do not last long in the refrigerator. Only about 3 to 4 days if it is raw. Then 1 to 2 days longer if cooked and placed in an airtight container. You should always cover meats when stored in the fridge.
They are both the same healthiness, unless the fresh have been on a supermarket shelf for a long time. In this case, the frozen may have kept it's nutrients better than the fresh. Bear in mind that frozen strawberries become unusable mushy if you defrost them - they're better off eaten frozen or cooked from frozen.
Most food used at fast food restaurants is frozen, so it is not actually fresh. How long it is frozen before it is used is not known. After food are cooked, there is a hold time for how long it can be kept under the warming lights. Foods like lettuce that cannot be frozen usually contain preservatives to make it look fresher longer, but it is not known for how long.
How long it will last will depend upon how good it was when frozen and how it was thawed. If it was thawed at room temperature, it should be cooked immediately. If it wasn't fresh when frozen, it should be cooked immediately. If it was very fresh when frozen and was thawed in the fridge, then you should have at least a couple days to cook it.
Embryos are frozed in liquid nitrogen through a process called cryofreezing. Embryos are generally frozen to be stored for long periods of time or if they have to be trasported to a different location.
