Cetaceans (baleen and toothed whales) present a unique set of adaptations for life in water. Among other abilities, the two living groups can hear and produce different sound frequencies: baleen whales use low frequencies primarily for communication, while toothed whales acquired the ability to echo...

Cetaceans (baleen and toothed whales) present a unique set of adaptations for life in water. Among other abilities, the two living groups can hear and produce different sound frequencies: baleen whales use low frequencies primarily for communication, while toothed whales acquired the ability to echolocate using high frequency sounds. Both groups exhibit modifications to the morphology of the ear bones (tympanic bulla and periotic) that closely track their behaviour and ecology. While the evolution of sound reception in whales is being thoroughly investigated, the changes in prenatal development (ontogeny) that generate these disparate ear bone morphologies remain mostly unknown. In this study, we characterize the ontogeny of the ear bones in Cetacea by looking at the progression of ossification and associated changes in morphology using a combination of traditional measurements and an innovative landmark-free method to quantify shape on a newly assembled 3D dataset spanning the ontogeny and phylogeny of ... : PLY files: A total of 75 specimens of Cetacea from 7 international museum collections, 28 Mysticeti (baleen whales) and 47 Odontoceti (toothed whales), spanning from embryos (<2 months from conception) to adults are analysed in this study for the tympanic bulla.
