Freezing Crab

[Rip'N'Lips]

So, I went out on Friday for 3 hours with my daughter and we scored. We ended up with 22, could of limited, but decided to count our lucky stripes. Brought them home and cooked up and had 3 left over. We love crab at our house and it got me wondering, can you freeze crab? I would love to vacuum pack them and have them year round. Has anyone pulled it off? What if I clean them, but don't cook them and throw them in the freezer, will I be in a hospital if I then eat them? Any ideas would be great.
