Add to ORKGdevil nThe predominant black spot on a haddock, just behind its eye was called the _devil's thumbprint_ by a working companion of mine this past summer. Pointing to a picture of a haddock on a wall chart, he asked me if I knew what the spot was. I said that I didn't and he said it was the devil's thumbprint. He said it jokingly and offered no explanation as to why it was called that.YesDNE-cit DICT CEN.NOV 16 1965 [check]Used I and SupUsed IUsed Iplay with the devil, PLAY, devil-ma-click, devil-ma-jig,~angel, ~birthday, ~blanket, ~feathers,~ cap, DEAD-MAN'S CAP, FAIRY, ~claw, ~fashion, FASHION,~ laughter, ~ match,~ pelt,~ pipe,~ racket, RACKET, devilskin,~ spit, SPIT, ~ thumb-print, ~ umbrellaChecked by Cathy Wiseman on Mon 26 Jan 2015;...
