In this case report, we present a rare occurrence of a narrow-ridged finless porpoise (Neophocaena asiaeorientalis sunameri), discovered on the coast of Jeju Island, Republic of Korea, that was afflicted…
Harbor porpoise aggregations in the Salish Sea
Anderson, Dave; Shuster, Laurie; Elliser, Cindy R.; MacIver, Katrina; Gless, Erin Johns; Krieger, Johannes; Hall, Anna
Oceans (2023)
Harbor porpoises are typically seen in small groups of 1–3 individuals, with aggregations of 20+ individuals treated as rare events. Since the 1990s, the harbor porpoise population in the Salish…

Sveegaard, S.
(2023)
In July 2022, Aarhus University was contracted by SWECO AB to conduct a one-year baseline study and impact assessment of harbour porpoises as well as noise monitoring within the pre-investigation…
Harbor porpoise losing its edge: Genetic time series suggests a rapid population decline in Iberian waters over the last 30 years
Ben Chehida, Yacine; Stelwagen, Tjibbe; Hoekendijk, Jeroen P. A.; Ferreira, Marisa; Eira, Catarina; Torres‐Pereira, Andreia; Nicolau, Lidia; Thumloup, Julie; Fontaine, Michael C.
Ecology and Evolution (2023)
Impact of climate change is expected to be especially noticeable at the edges of a species' distribution, where they meet suboptimal habitat conditions. In Mauritania and Iberia, two genetically differentiated…
Variations in echolocation click characteristics of finless porpoise in response to day/night and absence/presence of vessel noise
Ogawa, Mayu; Kimura, Satoko S.
PLOS ONE (2023)
Small odontocetes produce echolocation clicks to feed and navigate, making it an essential function for their survival. Recently, the effect of vessel noise on small odontocetes behavior has attracted attention…

The Shandong Peninsula is located on the western coast of the Pacific and is adjacent to the Bohai Sea (BS) and the Yellow Sea (YS) to the east. The East…
Variation of blubber thickness of the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) in human care: Adaptation to environmental temperature
Tang, Bin; Hao, Yujiang; Wang, Chaoqun; Deng, Zhengyu; Shu, Guilin; Wang, Kexiong; Wang, Ding
Water Biology and Security (2023)
Blubber thickness (BT) has a seasonal pattern in most small cetaceans in temperate and polar regions, which may be a crucial adaptive mechanism in response to environmental temperature changes. However,…
Millions of seafloor pits, not pockmarks, induced by vertebrates in the North Sea
Schneider von Deimling, Jens; Hoffmann, Jasper; Geersen, Jacob; Koschinski, Sven; Lohrberg, Arne; Gilles, Anita; Belkin, Igor; Böttner, Christoph; Papenmeier, Svenja; Krastel, Sebastian
Communications Earth & Environment (2023)
Seabed pockmarks are among the most prominent morphologic structures in the oceans. They are usually interpreted as surface manifestation of hydrocarbon fluids venting from sediments. Here we suggest an alternative…
Diving on damage – The muscle transcriptome of parasitic infested harbor porpoises (Phocoena phocoena) hints at oxidative stress but not hypoxia
Dönmez, Eda Merve; Siebert, Ursula; Fabrizius, Andrej
Frontiers in Marine Science (2023)
The only native cetacean in German waters, the harbor porpoise (Phocoena phocoena), is impacted by numerous pathological lesions in the respiratory tract mainly caused by parasites or bacteria. Although harbor…
