Wow. They look like real mean bar stewards with those claws. I used to go crabbing with my Dad and it was great fun. Fish hook, line and a chunk of meat, throw into the sea off a pier etc and wait for a few mins then pull out and often a crab was attached!! Some bigger than yours but nothing with claws like that!!
