Did you know that a frozen crab will come back to life months later if you thaw it? Thats not normal! They should be killed for that! I think they must be in league with Walt Disney's frozen head or something.
Either way, you will be happy to know that back in High School Marine Biology I got to dissect one while it was alive. I pinned the little fucker's arms and legs to the dissection pan and the removed its top shell while it sat and screamed in silent crabby horror. I got to touch it still beating heart.
Mark one win for the straight walking, 2 legged, non pincher bearing people!
