An Unparalleled Sexual Dimorphism of Sperm Whale Encephalization [PDF]
, 2016 The sperm whale Physeter macrocephalus (Linnaeus, 1758) is the largest toothed whales and possesses the highest absolute values for brain weight on the planet (together with the killer whale Orcinus orca).

Review of the tetrapod skull–neck boundary: implications for the evolution of the atlas–axis complex
Biological Reviews, Volume 100, Issue 6, Page 2435-2470, December 2025.ABSTRACT This review describes variation in modern and fossil occiput–atlas–axis complex anatomy of total group Tetrapoda with the aim of documenting the range of structural variation throughout their evolutionary history to establish grounds for comparison of the complex between tetrapod clades.

Diversity, 2023 The early diverging, dolphin-sized, cetacean clade Xenorophidae are a short-lived radiation of toothed whales (Odontoceti) that independently evolved two features long thought to be odontocete synapomorphies: the craniofacial and cochlear morphology ...

Establishing death in stranded Odontocetes (toothed whales) using other mammals : a pilot study : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Zoology at Massey University [PDF]
, 2003 The aim of this study was to investigate and evaluate a new method for determining death in stranded odontocetes (toothed whales). The new method was using the pulsations seen in the retinal blood vessels in the place of the heart rate. The retinal blood

Molecular Ecology, Volume 34, Issue 24, December 2025.ABSTRACT The marine environment comprises vast regions without physical barriers to movement, making the understanding of population isolation and the evolution of diversity challenging. This is especially the case for highly mobile marine species.

Frontiers in Ecology and Evolution, 2023 Teeth are often the first structures that anatomists and paleontologists examine to understand the ecology and morphology of feeding, both because teeth are highly specialized structures that provide precise information, and because they are among the ...

Experimental Physiology, Volume 110, Issue 12, Page 1917-1927, December 1, 2025.Abstract The common hippopotamus (Hippopotamus amphibius) shares a common terrestrial ancestor with whales (Cetacea) and has independently evolved similar physiological adaptations to their aquatic lifestyle. Although several studies have explored the electrical signalling in whale hearts, the understanding of the conduction system and electrical ...

Comparative Anatomy of the Bony Labyrinth (Inner Ear) of Placental Mammals. [PDF]
PLoS ONE, 2013 BACKGROUND:Variation is a naturally occurring phenomenon that is observable at all levels of morphology, from anatomical variations of DNA molecules to gross variations between whole organisms. The structure of the otic region is no exception.
