One day recently, Joseph and William Astrauckas of Atlanta, Ga., and their friend Brady Reeks decided to go crabbing as they usually do when on the Island and caught a once-in-a-lifetime surprise: a three-clawed crab. 

Joseph recalled, “We heard there was a really good spot to go crabbing, so we went there instead of down the street from my grandparents’ house. We put frozen bunker in three cage traps overnight.”
