Evaluation of insertion and deletion polymorphisms of Brazilian Odontoceti
Academia Biology, 2023 Brazilian Odontoceti strandings provide substantial information about distribution, health, and genetics of this suborder. Moreover, molecular identification is required and studies in this area have been developed to clarify their ...

A new large squalodelphinid (Cetacea, Odontoceti) from Peru sheds light on the Early Miocene platanistoid disparity and ecology [PDF]
Royal Society Open Science, 2018 The South Asian river dolphin (Platanista gangetica) is the only extant survivor of the large clade Platanistoidea, having a well-diversified fossil record from the Late Oligocene to the Middle Miocene.

Molecular Evidence for Relaxed Selection on the Enamel Genes of Toothed Whales (Odontoceti) with Degenerative Enamel Phenotypes [PDF]
GenesDifferent species of toothed whales (Odontoceti) exhibit a variety of tooth forms and enamel types. Some odontocetes have highly prismatic enamel with Hunter-Schreger bands, whereas enamel is vestigial or entirely lacking in other species.

Three‐Dimensional Vascular Structure of Caudal and Dorsal Fins of a Dwarf Sperm Whale [PDF]
Ecology and EvolutionPrevious studies have described two distinct vascular systems in cetacean fins. However, these studies have been limited to Delphinoidea species, with little information on their three‐dimensional structures. In this study, the anatomical analysis of the

Molecular evolution of toothed whale genes reveals adaptations to echolocating in different environments [PDF]
BMC GenomicsBackground Echolocation was a key development in toothed whale evolution, enabling their adaptation and diversification across various environments. Previous bioacoustic and morphological studies suggest that environmental pressures have influenced the ...

New heterodont odontocetes from the Oligocene Pysht Formation in Washington State, U.S.A., and a reevaluation of Simocetidae (Cetacea, Odontoceti) [PDF]
PeerJ, 2023 Odontocetes first appeared in the fossil record by the early Oligocene, and their early evolutionary history can provide clues as to how some of their unique adaptations, such as echolocation, evolved.

A Comparison of Fossils of the Two Whale Fam ilies: Physeteridae and Monodentidae (Cetacea) [PDF]
Mongolian Journal of Biological Sciences, 2016 Whales are a group of marine creatures that have elicited scientifi c and layman’s curiosity since long. The present paper has a focus on elucidating fossils of two Odontoceti families viz. Physeteridae and Monodentidae.
