Variation in size of gills, labial palps, and adductor muscle in<i>Mytilus edulis</i>L. (Bivalvia) from Danish waters

Abstract

Abstract Large variation is found in the size of gills, labial palps, and posterior adductor muscle in samples of Mytilus edulis L. from different parts of Danish waters. The differences in gill size and palp size can be explained as adaptation to waters of different turbidity, and most of the variation in adductor muscle size as adaptation to predation by Asterias.
