I think they're dungeness. I bought two of them and they had lots of flesh. Just outstanding value and quality. Good sized crabs. The lobsters are not as great (not much flesh inside the shell).
I would run and not walk to get these crabs and buy as many as you can handle.
Easiest way to enjoy it is by boiling it for a few minutes (remove the dirty parts first). Then buy the seafood chili sauce that I told you guys about. You can get it at the Indonesian section at the market. It's orange in color and the bottle is about 8 inches tall. Get the brand "sambal selera" or the ABC brand.
