The video link below was done by Tim Sughrue of Congressional Seafood over at a sloughing house in Kent Island, MD. In the video you can see how much larger the soft shell crab is than the shell it burst from. Remember, you have to be quick to catch the crabs at the perfect moment when they first release their shell, because immediately after they begin to harden. This requires round-the-clock watch with workers keeping an eye on the crabs through the night. It's a labor of love, but anyone who's eaten a great soft shell crab will tell you its worth it!
