A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica). [PDF]
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales. [PDF]
This study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

Genomic Insights Into the Evolutionary History of Berardius Beaked Whales: Speciation Driven by Resource Specialization, Gigantism and Thermal Barriers? [PDF]
ABSTRACT Understanding the diversity of our oceans is fundamental now more than ever as climate change and human activities put increasing pressure on marine species and ecosystems. Beaked whales (family Ziphiidae) are among the most poorly understood marine mammals, in part due to their affinity to offshore underwater canyons and prolonged diving ...
