Frozen Live Blue Crab

I got some whole blue crabs at Vallis covered in plasic. They look uncooked and they aren't moving and I froze them. How long can they be in the freezer and are they safe to eat?

To ensure safe consumption, you should boil those blue crabs and clean them or vise versa...clean them and boil them up. Then, you can either eat them or properly package them and freeze them.
Keeping uncleaned and unboilded crabs, whether they are blue or any other types of crab, and freezing them before cleaning and boiling is not safe practice if you plan on eating them.
This goes for blue crabs in soft shell form as well.
