Asymmetry of the nasofacial skull in toothed whales (Odontoceti)
Abstract In this study, the nasal asymmetry of odontocetes (toothed whales) was analyzed morphometrically by placing landmarks on photographed nasofacial skulls from 12 different species and genera that belong to four odontocete families. The results show that the degree of asymmetry tends to be lin...
