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 ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Geographical and Seasonal Distribution of Australian Pygmy Right Whales (Caperea marginata) Based on Passive Acoustics

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT The pygmy right whale (Caperea marginata) is one of the least studied mysticete species. To shed light on its geographic and seasonal distribution, we compiled archival acoustic recordings from 26 sites across southern Australia and developed a deep‐learning detector for pygmy right whale “doublet” vocalizations.

Salishicetus meadi, a new aetiocetid from the late Oligocene of Washington State and implications for feeding transitions in early mysticete evolution

open access: yesRoyal Society Open Science, 2018
Living baleen whales, or Mysticeti, lack teeth and instead feed using keratinous baleen plates to sieve prey-laden water. This feeding strategy is profoundly different from that of their toothed ancestors, which processed prey using the differentiated ...

2006 progress report on acoustic and visual monitoring for cetaceans along the outer Washington Coast [PDF]

open access: yes, 2007
An acoustic and visual monitoring effort for cetaceans was initiated within the boundaries of the proposed expansion area for the Quinault Underwater Tracking Range in July 2004.

A new Early Oligocene toothed ‘baleen’ whale (Mysticeti: Aetiocetidae) from western North America: one of the oldest and the smallest [PDF]

open access: yesRoyal Society Open Science, 2015
Archaic toothed mysticetes represent the evolutionary transition from raptorial to bulk filter feeding in baleen whales. Aetiocetids, in particular, preserve an intermediate morphological stage in which teeth functioned alongside a precursor of baleen ...

Living Near the Surface: Dive Behavior of Sei Whales (Balaenoptera borealis) in the Southwestern Atlantic Ocean

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Understanding the diving behavior of baleen whales in tropical breeding areas is essential for evaluating both ecological functions and anthropogenic threats. In this study, we combined satellite transmitters and generalized additive mixed models (GAMMs) to investigate the dive behavior of sei whales (Balaenoptera borealis) in Santos Basin (SB)
