Mammal endemism In Italy: A review [PDF]
, 2018 Although there are various checklists of Italian mammals, there is not yet a synthesis of those mammals that are endemic to Italy. Therefore, we provide for the first time a detailed review on Italian mammal endemic species including endemic taxa ...

Coexistence of Oligocene toothed and baleen-assisted mysticetes in the northwestern Pacific [PDF]
Fossil RecordOligocene mysticetes display an unparalleled diversity and morphological disparity in the evolutionary history of Mysticeti. However, their paleoecological aspects, such as the patterns of coexistence of different morphotypes, remain poorly explored ...

BMC Ecology and Evolution, 2023 Modern baleen whales are unique as large-sized filter feeders, but their roles were replicated much earlier by diverse marine reptiles of the Mesozoic.

Anatomy, feeding ecology, and ontogeny of a transitional baleen whale: a new genus and species of Eomysticetidae (Mammalia: Cetacea) from the Oligocene of New Zealand [PDF]
PeerJ, 2015 The Eocene history of cetacean evolution is now represented by the expansive fossil record of archaeocetes elucidating major morphofunctional shifts relating to the land to sea transition, but the change from archaeocetes to modern cetaceans is poorly ...

Humpback Whale (Megaptera novaeangliae) Song on a Subarctic Feeding Ground
Frontiers in Marine Science, 2021 Male humpback whales (Megaptera novaeangliae) are known to produce long complex sequences of structured vocalizations called song. Singing behavior has traditionally been associated with low latitude breeding grounds but is increasingly reported outside ...

Early stages of tooth development in the harbor porpoise Phocoena phocoena
The Anatomical Record, EarlyView.Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

, 2022 Whales, order Cetacea, are divided on suborder Mysticeti, baleen whales and Odontoceti, toothed whales depending on structure of their jaws. Baleen whales are pelagic animals and they feed on plankton and fish. Instead of teeth they have baleen or keratin plates attached to edges of their maxilla. Toothed whales are carnivous animals.

The dopamine receptor D5 gene shows signs of independent erosion in toothed and baleen whales [PDF]
PeerJ, 2019 To compare gene loci considering a phylogenetic framework is a promising approach to uncover the genetic basis of human diseases. Imbalance of dopaminergic systems is suspected to underlie some emerging neurological disorders. The physiological functions

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model
Integrative Zoology, EarlyView.UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT Humpback whales (Megaptera novaeangliae) from breeding stock A migrate annually between Antarctic feeding grounds (~65° S) and Brazilian breeding areas (~17° S). Traditionally considered to fast during migration, recent feeding observations and increased strandings along southeastern Brazil (~23° S) raise questions about possible shifts in ...
