The term 'whorls' refers to a pattern of concentric circles or SPIRALS that can be found in many natural objects, such as fingerprints, shells, and plants. In crosswords, the solutions for whorls are 'EDDIES' (6 letters) and 'SPIRALS' (7 letters). An eddy is a small circular current of water or air that moves in the opposite direction of the main flow. A spiral is a curved line that winds around a central point, gradually increasing in size as it moves outward.
