Aquatic Mammals (2019)
Social group dynamics are known to impact odontocetes’ health and welfare in captivity. Social dominance and agonistic interactions that occur to establish and maintain these relationships might express themselves differently…
The bacterial diversity in infected tissue pus of an East Asian finless porpoise
Wu, Caiwen; Hong, Zhe; Ibrahim, Aamir; Zhang, Di; Wang, Lin; Li, Ting; Chen, Bingyao
African Journal of Microbiology Research (2019)
Two East Asian finless porpoises (Neophocaena asiaeorientalis sunameri) in Ningbo, East China Sea, China, were observed to be bacterially infected between the fat layer and muscle layer. The microbial communities…
Histological variation in blubber morphology of the endangered East Asian finless porpoise (Neophocaena asiaeorientalis sunameri) with ontogeny and reproductive states
Ji, Junhua; Nabi, Ghulam; Zeng, Xianyuan; Hao, Yujiang; Wang, Ding
Zoological Studies (2019)
The highly lipid-rich blubber in the hypodermis is a specialized structure that functions in thermoregulation, energy storage, buoyancy control, locomotion, and streamlining the body shape in marine mammals. The key…
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,…
Abundance decline in the narrow‐ridged finless porpoise population off the Pacific coast of eastern Japan

Acta Hydrobiologica Sinica (2019)
Jiangxi Province is one of the most important distribution of Yangtze finless porpoise (YFP). Since the scientific investigation of Yangtze finless porpoise in the whole Yangtze River basin in 2017,…
Porpoises the world over: Diversity in behavior and ecology
Teilmann, Jonas; Sveegaard, Signe
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…
Social responses of travelling finless porpoises to boat traffic risk in Misumi West Port, Ariake Sound, Japan
Morimura, Naruki; Mori, Yusuke
PLOS ONE (2019)
Anthropogenic effects have created various risks for wild animals. Boat traffic is one of the most fatal risks for marine mammals. Individual behavioral responses of cetaceans, including diving behavior such…
First evaluation of legacy persistent organic pollutant contamination status of stranded Yangtze finless porpoises along the Yangtze River Basin, China
Zhang, Kai; Qian, Zhengyi; Ruan, Yuefei; Hao, Yujiang; Dong, Weiwei; Li, Ke; Mei, Zhigang; Wang, Kexiong; Wu, Chenxi; Wu, Jianhong; Zheng, Jinsong; Lam, Paul K. S.; Wang, Ding
Science of The Total Environment (2020)
Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis), inhabiting the Yangtze River, are an endangered species in China. They are threatened by various kinds of pollutants, among which persistent organic pollutants (POPs)…
Underwater noise pollution in China’s Yangtze River critically endangers Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)
