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

Soviet Illegal Whaling: The Devil and the Details [PDF]
, 2011 In 1948, the U.S.S.R. began a global campaign of illegal whaling that lasted for three decades and, together with the poorly managed “legal” whaling of other nations, seriously depleted whale populations.

Journal of Fish Biology, EarlyView.Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Retrophylogenomics in rorquals indicate large ancestral population sizes and a rapid radiation
Mobile DNA, 2019 Background Baleen whales (Mysticeti) are the largest animals on earth and their evolutionary history has been studied in detail, but some relationships still remain contentious.

How deep can baleen whales dive? [PDF]
Marine Ecology Progress Series, 1999 This paper presents evidence of deep diving performances by fin whales Balaenoptera physalus in the Mediterranean Sea, never directly recorded for any other species of baleen whales. By means of velocity-time-depth-recorders applied to the whales with suction cups, depths of at least 470 m were registered twice, over 7 dives below 150 m recorded during

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 ...

Oral cavity hydrodynamics and drag production in Balaenid whale suspension feeding. [PDF]
PLoS ONE, 2017 Balaenid whales feed on large aggregates of small and slow-moving prey (predominantly copepods) through a filtration process enabled by baleen. These whales exhibit continuous filtration, namely, with the mouth kept partially opened and the baleen ...
