These photographs of mantis shrimps are taken through polarizing filters rotated to be vertical in the top 2 and horizontal in the bottom 2 (see arrows). Note the difference in color which results on the paddles at the front (left photos) and back (right photos.) of the animal. Photographs by close collaborator and the world stomatopod expert Roy Caldwell.
