Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Intraspecific variation of cochlear morphology in bowhead and beluga whales

open access: yesThe Anatomical Record, Volume 309, Issue 6, Page 1514-1529, June 2026.
Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

Genetic and Ecological Divergence Between Northwest Atlantic Killer Whale Populations

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Killer whale (Orcinus orca) populations exhibit substantial genetic, ecological, and morphological differences across their global distribution. In this study, we use whole‐genome resequencing and compound‐specific stable isotope analysis of amino acids to show concurrent genetic and ecological differentiation in two relatively understudied killer ...
