MANDIBULAR AND DENTAL VARIATION AND THE EVOLUTION OF SUCTION FEEDING IN ODONTOCETI [PDF]

Journal of Mammalogy, 2006
Comprehensive morphometric analysis of osteological and necropsy specimens indicates that blunt heads and wide jaws, both of which create a more circular mouth opening and thus improve water flow for suction feeding, are common in Odontoceti and found in all families except freshwater river dolphins (Platanistoidea), which are exclusively long-snouted.

Cellular Composition of the Brain of a Northern Minke Whale

Journal of Comparative Neurology, Volume 533, Issue 9, September 2025.
Avelino‐de‐Souza et al. show that the minke whale has 3.2 billion neurons in the cerebral cortex, as predicted for a generic cetartiodactyl species, which places it and other cetaceans between monkeys and great apes in a ranking of mammal and bird species by total numbers of neurons in the pallium/cerebral cortex.

μCeta: A Set of Cetacean‐Specific Primers for Environmental DNA Metabarcoding With Minimal Amplification of Non‐Target Vertebrates

Environmental DNA, Volume 7, Issue 5, September–October 2025.
Cetacean eDNA metabarcoding results from the aquarium pool samples using new cetacean‐specific primers. μCeta shows superior performance to detect and differentiate different cetacean species. ABSTRACT Biodiversity monitoring is crucial for understanding ecosystem dynamics and species distributions, particularly in the context of anthropogenic impacts ...

Further Evidence for Breeding White-Beaked Dolphin (Lagenorhynchus albirostris) in Inner Danish Waters

Coasts
The white-beaked dolphin (Lagenorhynchus albirostris) is the second most frequently stranded cetacean species along the Danish coastline. The northern North Sea, the Skagerrak, the Kattegat and the Danish straits are part of the species distributional ...

Convergent evolution in toothed whale cochleae

BMC Evolutionary Biology, 2019
Background Odontocetes (toothed whales) are the most species-rich marine mammal lineage. The catalyst for their evolutionary success is echolocation - a form of biological sonar that uses high-frequency sound, produced in the forehead and ultimately ...

Morphological convergence in ‘river dolphin’ skulls [PDF]

PeerJ, 2017
Convergent evolution can provide insights into the predictability of, and constraints on, the evolution of biodiversity. One striking example of convergence is seen in the ‘river dolphins’.

Generating Spatialised and Seasonal Deep‐Time Palaeoclimatic Information: Integration Into an Environmental‐Dependent Diversification Model

Global Ecology and Biogeography, Volume 34, Issue 4, April 2025.
ABSTRACT Aim Testing the impact of climate on diversification is a major goal of evolutionary biology. Birth‐death models like palaeoenvironment‐dependent diversification (PDD) models, for example, allow exploring the potential correlations between diversification dynamics and past environmental changes, such as temperature, among other abiotic ...

A new inioid (Cetacea, Odontoceti, Delphinida) from the Miocene of Peru and the origin of modern dolphin and porpoise families

, 2017
In this paper we describe Brujadelphis ankylorostris gen. nov., sp. nov., a new delphinidan (Cetacea, Odontoceti, Delphinida), based on a well-preserved skull with ear bones, associated mandibles, most of the teeth in situ and a fragment of the atlas ...
