(Anales del Instituto de Biología serie Zoología, 2009)
Carbon productivity and flux in the marine ecosystems of the Galapagos Marine Reserve based on cetacean abundances and trophic indices
(Universidad de Valparaíso. Facultad de Ciencias del Mar, 2009)
First record of a macroraptorial sperm whale (Cetacea, physeteroidea) from the miocene of Argentina
(Sociedade Brasileira de Paleontologia, 2018-09)
Raptorial sperm whales of the genus Livyatan were described from the Miocene of Peru and Chile. Revision of paleontological collections resulted in the finding of isolated teeth belonging to aff. Livyatan sp. coming from ...
Trophic relationships between sperm whales and the jumbo squid using stable isotopes of C and N
(Marine Ecology Progress Series, 2004)
The trophic position and the predator–prey relationship between the sperm whale Physeter macrocephalus and the jumbo squid Dosidicus gigas were examined by measuring stable isotope ratios of carbon and nitrogen. Skin samples ...
The social organization of sperm whales in the Gulf of California and comparisons with other populations
(Journal of the Marine Biological Association of the United Kingdom, 2009)
Intra-specific variation in social organization provides valuable insights into the selective forces driving social evolution. Sperm whales are distributed globally and live far from shore, thus obtaining large sample sizes ...
Diving behavior of sperm whales in relation to behavior of a major prey species, the jumbo squid, in the Gulf of California, Mexico
(Marine Ecology Progress Series, 2007)
Sperm whales occur worldwide and feed largely on meso- and bathypelagic squid, but little is known about the behavioral ecology of this predator and its prey. In the Gulf of California, sperm whales are thought to feed on ...

Systematic revision of a Miocene sperm whale from Patagonia, Argentina, and the phylogenetic signal of tympano-periotic bones in Physeteroidea
(Polish Academy of Sciences. Institute of Paleobiology, 2021-01)
Sperm whales (Physeteroidea) include today only two genera of morphologically disparate odontocetes: the largest toothed whale known (Physeter macrocephalus) and small sized forms (Kogia spp.). In contrast, their fossil ...
