Lipids of lung and lung fat emboli of the toothed whales (Odontoceti) [PDF]
Scientific Reports, 2020 AbstractLipids are biomolecules present in all living organisms that, apart from their physiological functions, can be involved in different pathologies. One of these pathologies is fat embolism, which has been described histologically in the lung of cetaceans in association with ship strikes and with gas and fat embolic syndrome.

Life Expectancy in Marine Mammals Is Unrelated to Telomere Length but Is Associated With Body Size
Frontiers in Genetics, 2021 Marine mammals vary greatly in size and lifespan across species. This study determined whether measures of adult body weight, length and relative telomere length were related to lifespan.

Rivista Italiana di Paleontologia e Stratigrafia, 2021 Among the many hyper-longirostrine dolphins (Odontoceti) from the Miocene, members of the family Eurhinodelphinidae bear two highly distinctive cranial features: a long and edentulous premaxillary portion of the rostrum and a mandible that is ...

Contribution to the Knowledge of Cetacean Strandings in Chile between 2015 and 2020
OceansStrandings caused by anthropogenic factors are one of the most worrying threats in relation to the conservation of cetacean species, and in the case of Chile, due to its geography and large extension of the coastline, monitoring and access to these ...

Wonky whales: the evolution of cranial asymmetry in cetaceans
BMC Biology, 2020 Background Unlike most mammals, toothed whale (Odontoceti) skulls lack symmetry in the nasal and facial (nasofacial) region. This asymmetry is hypothesised to relate to echolocation, which may have evolved in the earliest diverging odontocetes.

A new kogiid sperm whale from northern Italy supports psychrospheric conditions in the early Pliocene Mediterranean Sea [PDF]
Acta Palaeontologica Polonica, 2019 Among living cetaceans, dwarf and pygmy sperm whales (Kogia) are the only members of the family Kogiidae, regarded as diminutive and elusive relatives of the great sperm whale Physeter. Kogiids are known as fossils by several skulls, teeth, and ear bones
