Hearing from the ocean and into the river: The evolution of the inner ear of Platanistoidea (Cetacea, Odontoceti)

Mariana Viglino, Maximiliano Gaetán, Mónica R. Buono, R. Ewan Fordyce & Travis Park
The inner ear of the two higher clades of modern cetaceans (Neoceti) is highly adapted for hearing infrasonic (mysticetes) or ultrasonic (odontocetes) frequencies. Within odontocetes, Platanistoidea comprises a single extant riverine representative, Platanista gangetica, and a diversity of mainly extinct marine species from the late Oligocene onward. Recent studies, drawing on features including the disparate tympanoperiotic, have not yet provided a consensus phylogenetic hypothesis for platanistoids. Further, cochlear morphology and evolutionary patterns have never been...
