Resumen:
Transitions to and from aquatic life involve transformations in sensory systems.The Ross seal, Ommatophoca rossii, offers the chance to investigatethe cranio-sensory anatomy in the most aquatic of all seals. The use ofnon-invasive computed tomography on specimens of this rare animalreveals, relative to other species of phocids, a reduction in the diametersof the semicircular canals and the parafloccular volume. These features areindependent of size effects. These transformations parallel those recordedin cetaceans, but these do not extend to other morphological features suchas the reduction in eye muscles and the length of the neck, emphasizingthe independence of some traits in convergent evolution to aquatic life.
