Comparative anatomy of the bony labyrinth of extant and extinct porpoises (Cetacea: Phocoenidae)

Racicot, Rachel A.; Gearty, William; Kohno, Naoki; Flynn, John J.
Biological Journal of the Linnean Society (2016)

The inner ear anatomy of cetaceans, now more readily accessible by means of nondestructive high-resolution X-ray computed tomographic (CT) scanning, provides a window into their acoustic abilities and ecological preferences.…


Comparative morphology of porpoise (Cetacea: Phocoenidae) pterygoid sinuses: Phylogenetic and functional implications

Racicot, Rachel A.; Berta, Annalisa
Journal of Morphology (2012)

High-resolution X-ray computed tomographic scans were used to examine pterygoid sinus morphology within extant porpoise species and one delphinid (Tursiops truncatus), in order to consider: 1) intraspecific and interspecific variation…


Cestodes from Hector’s beaked whale (Mesoplodon hectori) and spectacled porpoise (Phocoena dioptrica) from Argentinean waters

Nikolov, Pavel N.; Cappozzo, H. Luis; Berón-Vera, Bárbara; Crespo, Enrique A.; Raga, J. Antonio; Fernández, Mercedes
Journal of Parasitology (2010)

Single individuals of 2 little-known cetacean species, Mesoplodon hectori and Phocoena dioptrica, stranded and died on the coast of Argentina (Buenos Aires and Chubut provinces, respectively) and were studied for…


Odontocetes of the Southern Ocean Sanctuary

Van Waerebeek, K.; Leaper, R.; Baker, A. N.; Papastavrou, V.; Thiele, D.; Findlay, K.; Donovan, G.; Ensor, P.
Journal of Cetacean Research and Management (2010)

Twenty-eight odontocete species were identified as occupying sub-Antarctic and Antarctic habitat covered by the 1994 IWC-established Southern Ocean Sanctuary. Toothed whales evidently play an important part in the Antarctic polar…


Parasites in stranded cetaceans of Patagonia

Berón-Vera, Bárbara; Crespo, Enrique A.; Raga, Juan A.
Journal of Parasitology (2008)

There is an increasing interest in parasites of marine mammals of Argentina. Here, we examined several poorly known cetaceans, i.e., 2 spectacled porpoises and 1 Burmeister's porpoise (Phocoenidae), and 1…

Journal of Cetacean Research and Management (2006)

Most knowledge on the biology and ecology of the spectacled porpoise (Phocoena dioptrica) has been obtained from stranded specimens, with less than fifteen confirmed sightings in the sea. Published photographs…
