Histology of the grooved ventral pouch of the minke whale, Balaenoptera acutorostrata , with special reference to the occurrence of lamellated corpuscles
The rorquals, Balaenopteridae, catch their food by swimming into a concentration of krill or schooling fish, taking up prey-laden water, and then filtering it with their fringed baleen. An anatomical feature adapted to this feeding strategy is the expansible buccal cavity. The amount of expansion de...
