One of the greatest mysteries in the study of Cetacea[aquatic mammals] has always been that the creatures found in the stomachs of toothed whales show no teeth marks. Now a University of California at Santa Cruz professor thinks he may have solved the enigma with what he calls the “big bang” theory of cetacean predation. 8&f}GdZh
Ken Norris, natural history professor, believes that rather than use their teeth to attack their victims, toothed whales stun their prey with intense bursts of sound. He points out that all 68 species of odontocetes (a sub-order that includes dolphins) use sound to locate their victims, and suggests this ability may have evolved to the point where it could be used as a weapon. )%f]`<
