Sensory anatomy of the most aquatic of carnivorans: the Antarctic Ross seal, and convergences with other mammals
Transitions to and from aquatic life involve transformations in sensory systems. The Ross seal, Ommatophoca rossii, offers the chance to investigate the cranio-sensory anatomy in the most aquatic of all seals. The use of non-invasive computed tomography on specimens of this rare animal reveals, rela...
