A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica). [PDF]

Anat Rec (Hoboken)
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

Seasonal dynamics of occurrence and group size of three species of cetaceans (Delphinidae and Phocoenidae) on the southwestern coast of the Black Sea

Scientia Marina, 2020
The spatial and temporal occurrence of cetaceans in the Black Sea and particularly along its southwestern coastline is poorly studied. Based on a total of 609 encounters, we present the analysis of monthly dynamics of (1) the numbers of cetacean ...

Testicular morphology and spermatogenesis in harbour porpoises (Phocoena phocoena) [PDF]

Theriogenology, 2019
Knowledge about reproductive parameters in male harbour porpoises such as testicular histology and germ cell maturation as well as seasonal changes in spermatogenesis is scarce. Thus, the aim of the present study was to report changes in the histological appearance of the testicular morphology of neonatal and juvenile harbour porpoises during ...
