How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales. [PDF]
J AnatThis study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

Astrocyte properties in cetacean cortices. [PDF]
Physiol RepAbstract Cetacean neurons are far more extensively studied in the scientific literature than the other principal cell type of the central nervous system—glia. To help address this knowledge gap, the current study profiled astrocytes in five cetacean species—Tursiops truncatus (Tt), Orcinus orca (Oo), Ziphius cavirostris (Zc), Pseudorca crassidens (Pc),

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

Borealodon osedax, a new stem mysticete (Mammalia, Cetacea) from the Oligocene of Washington State and its implications for fossil whale-fall communities [PDF]
Royal Society Open Science, 2019 Baleen whales (mysticetes) lack teeth as adults and instead filter feed using keratinous baleen plates. They do not echolocate with ultrasonic frequencies like toothed whales but are instead known for infrasonic acoustics.

Diversity and Consequences of Social Network Structure in Toothed Whales
Frontiers in Marine Science, 2021 Toothed whales (suborder Odontoceti) are highly social, large brained mammals with diverse social systems. In recent decades, a large body of work has begun investigating these dynamic, complex societies using a common set of analytical tools: social ...
