Dear Colleagues, on behalf of my co-authors and others who contributed to this work, please see the following open access article: The genus Neophocaena includes two species, the Indo-Pacific finless porpoise (N. phocaenoides) and the narrow-ridged finless porpoise (N. asiaeorientalis). The Indo-Pacific species is found in coastal waters from the Persian Gulf through south and southeast Asia to as far north as the Taiwan Strait. The narrow-ridged finless porpoise ranges from the Taiwan Strait to the waters of northern China, Korea, and Japan. Within N. asiaeorientalis there are two subspecies, the Yangtze finless porpoise (N. a. asiaeorientalis), found in the Yangtze River and adjoining lakes in China, and the East Asian finless porpoise (N. a. sunameri), found in coastal marine waters of China (including Hong Kong and Taiwan), Korea, Japan. In 2019, an international workshop was held on finless porpoise research and conservation. Participants shared that, in many regions, information on distribution, abundance and population structure is lacking or inadequate. A global assessment of research is critical to provide a basis for conservation planning. Anthropogenic activities (i.e., habitat degradation, pollution, etc.) are known threats, with fisheries bycatch the primary threat throughout the known distribution of finless porpoises. To conserve these cetaceans, research priorities include studies of abundance and distribution, habitat and ecology, fisheries-related mortality, increased public awareness, and bycatch mitigation. https://doi.org/10.1016/j.watbs.2024.100334 Ellen Hines, PhD Estuary & Ocean Science Center Professor Emeritus, School of the Environment San Francisco State University 3150 Paradise Dr Tiburon, CA. 94940 ehines@sfsu.edu<mailto:ehines@sfsu.edu> https://eoscenter.sfsu.edu/ellen-hines Adjunct Scientist: Center for Coastal Studies, Provincetown, MA
