WebAug 2, 2024 · Many aspects of cetacean morphology ultimately aid them in reducing drag, the resistance to movement in water, while also providing better means of maneuverability, and lift and thrust production (Reidenberg 2007).Most noticeably, their characteristic body shape combats drag by having a rounded front edge of their beak-like rostrum, a wider … WebIn this comparative, comprehensive review, we describe tongue structure and function within all cetacean lineages relative to other mammals, including artiodactyl relatives and other aquatic animals. We outline numerous tongue functions, distinguishing processes related to feeding on solid food from functions unrelated to solid food (Table 1).
