Morphology of the tympanic‐basicranial region in Mirounga leonina (Phocidae, Carnivora), postnatal ontogeny and sexual dimorphism
The ontogenetic trajectory of the tympanic bulla of the southern elephant seal, Mirounga leonina, is described and analyzed, with clear morphological differences observed between CI individuals, on one hand, and CII individuals plus CIII females on the other.

This character analysis shows the transformations that have occurred in the evolution of middle ear ossicles in pinnipeds and identifies diagnostic features of many of its clades.

The use of non-invasive computed tomography on specimens of this rare animal reveals a reduction in the diameters of the semicircular canals and the parafloccular volume, emphasizing the independence of some traits in convergent evolution to aquatic life.
Aggregation of mummified adult crabeater seals (Pinnipedia: Phocidae) in the eastern Antarctic Peninsula: age and sex structure, taphonomy and cause of death
This is exceptional as it is the first report of mostly adult female seals to strand in Antarctica and refutes the theory that only young animals are prone to stranding.
Integument in Antarctic seals: A comparative study and its relation to extreme environments
An exhaustive histological description of the integument Antarctic seals through different methodological approaches in a comparative framework is performed to link the histological features to their different lifestyles.
I've got you under my skin: inflammatory response to elephant seal's lice
During fieldwork in Patagonia and Antarctica, skin samples with lice within were collected for histological analysis to assess whether these parasites caused damage to the host.

The ontogeny and sexual dimorphism of the auditory region of Otaria byronia is described and explored for the first time, and the external and internal morphology of the tympanic bulla in both sexes and across different stages (bioclasses) is provided.
