Ethology and Behavioral Ecology of Odontocetes (2019)
Unlike the large number of species of true dolphins, there are only seven porpoise or phocoenid species, inhabiting different habitats and climate zones. They range from ice-covered water in the…
Position at birth and possible effects on calf survival in finless porpoises (Neophocaena asiaeorientalis)
Deng, Xiaojun; Hao, Yujiang; Serres, Agathe; Wang, Kexiong; Wang, Ding
Aquatic Mammals (2019)
Odontocetes are usually reported giving birth to calves in breech position (fluke-first). Cephalic position (head-first) is less frequently observed and, therefore, is considered to be abnormal for the parturition. However,…

Theriogenology (2010)
The use of ultrasonography as a noninvasive tool for assessing the reproductive status of the male Yangtze finless porpoise (YFP; Neophocaena phocaenoides asiaeorientalis) was validated by correlating ultrasonographically determined testicular…
Population- and growth-related differences in helminthic fauna of finless porpoises (Neophocaena asiaeorientalis) in five Japanese populations

Marine Policy (2015)
In the present study, the species composition, geographical and seasonal patterns of strandings, bycatches and injuries of aquatic mammals reported in Chinese mainland waters, from 2000 to 2006, were analyzed…
Long-term effectiveness of pingers on a small population of finless porpoises in Japan
Amano, M.; Kusumoto, M.; Abe, M.; Akamatsu, T.
Endangered Species Research (2017)
Finless porpoises Neophocaena spp. are under pressure from various anthropogenic impacts due to their coastal habitat. Net fishery bycatch is considered a major risk for the populations around Japan, and…
