Ecological Factors Driving Cranial Morphology in Delphinidae

open access: yes, 2021
Delphinidae have a highly modified skull, resulting from their secondary adaptation to a fully aquatic lifestyle. This is characterized by skull telescoping and the posterior migration of the nasal bones, resulting in a vertical arrangement of the nasal passages, facilitating breathing at the water surface. Across the family, skull shape is notoriously
