Article Abstract
A female Cuvier's Beaked Whale () specimen measuring 580 cm in length died after being stranded in Southeastern Brazil. Following a necropsy, organ samples were obtained, fixed in 10% neutral buffered formalin and histopathologically analyzed. A severe and generalized hypodermis infection by (Phyllobothriidae) was observed, resulting in granulomatous panniculitis. Severe renal and arterial lesions were also noted, including a severe bone metaplasia in the aorta artery, associated with a massive infection by sp, (Tetrameridae). A significant thoracic hemorrhage due to thoracic aorta artery rupture was noted, also likely due to this infection, resulting in a fatal injury. This study contributes towards knowledge on histopathologic changes in the scarcely studied Cuvier's Beaked Whale, is the first to associate a sp. infection in this whale species in the Brazilian region and also the first to indicate a resulting osseous metaplasia due to this parasitism and granulomatous dermatitis associated with . Furthermore, this is also, to the best of our knowledge, the first report of cysts in a specimen to date.

The Caprera Canyon, a submarine canyon system off Sardinia in the western Mediterranean, was thought to be an important cetacean habitat, though studies on the area remained limited. To address this knowledge gap, 216 boat-based surveys were conducted between 2011 and 2019, covering 8443 km, using both research and whale-watching vessels. The distribution, diversity, relative abundance (Encounter Rate - ER), and habitat use of cetaceans were described, along with relevant behavioural and ecological observations.

Cuvier's beaked whale (CBW) (Ziphius cavirostris) is a cosmopolitan species known for its remarkable diving capabilities and is widely distributed across most seas and oceans, including the waters surrounding the Canary Islands. This species frequently exhibits a high prevalence of parasitism by the nematode Crassicauda spp., which affects the kidney, urinary tract, and arterial walls via larval migration, and is considered one of the primary natural causes of mortality among CBWs in the Canary archipelago.

Article Synopsis
- This study presents a novel in vitro muscle-derived cell line from a stranded male Cuvier's Beaked whale, facilitating research on its myogenic cells.
- The characterization involved various assays that assessed growth rate, fusion index, and chromosomal analysis, showing the cells' capability to fuse into multinucleated myotubes over time.
- The findings highlight the potential of this whale cell line for understanding cetacean muscle physiology and assessing the impacts of water pollutants through in vitro models.
