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

Kitovi usani, Mysticeti [PDF]

, 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

Comparing Drone and Vessel‐Based Imaging to Quantify Epibiont Coverage on Humpback Whales

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Cetacean epibionts offer noninvasive insights into host health, physiology, and spatial ecology, yet quantitative assessments in wild populations remain scarce. Although vessel‐based observations may be limited by field of view and analyst input, unoccupied aerial vehicles (UAVs; drones) are increasingly used to monitor cetacean health indices,

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, Volume 309, Issue 9, Page 2262-2285, September 2026.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Stable Isotope Analysis (δ13C and δ15N) of Baleen Plates Reveals Feeding Patterns in Stranded Humpback Whales (Megaptera novaeangliae) Along the Brazilian Coast

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 ...

First Stranding Event of a Common Minke Whale (Balaenoptera acutorostrata Lacépède, 1804) Reported in the Gulf of Thailand

Diversity, 2023
On 5 September 2022, a dead baleen whale was found stranded at Laem Phak Bia, Phetchaburi, the Gulf of Thailand, Thailand but could not be identified because it was in an advanced stage of decomposition.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

PHYLOGENETIC IMPLICATIONS OF SKULL STRUCTURE AND FEEDING BEHAVIOR IN BALAENOPTERIDS (CETACEA, MYSTICETI) [PDF]

Journal of Mammalogy, 2005
Abstract Balaenopteridae actively feed by engulfment. They swim rapidly at their prey (40–50 km/h), with their mouth open and their lower jaw pulled wide open at a 90° angle. Their mouth and ventral pouch engulf up to 60 m3 of water, then the mouth closes and food is swallowed after the expulsion of water through the baleen.
