Red List

Assessments or reassessments of 19 cetacean species, subspecies and populations were published on the IUCN Red List in 2017.  These included all four species of humpback dolphin, the Irrawaddy dolphin, two species of finless porpoise, the South Asian River dolphin, the beluga, the narwhal, and...

The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis), the world’s only freshwater porpoise, has been upgraded to Critically Endangered on the IUCN Red List of Threatened Species. This follows the recent probable extinction of the other cetacean once found in China’s Yangtze River system, the Yangtze...

The Fiordland subpopulation of common bottlenose dolphins (Tursiops truncatus) inhabits the fiords and bays of Fiordland, a mountainous, rainforest-covered World Heritage Area in the southwest of New Zealand’s South Island.  These dolphins are at the southern limit of the species’ global range and recent studies...

CSG member John Wang and collaborators recently presented strong morphological and molecular evidence for reproductive isolation of two main forms of finless porpoises in sympatry, leading to the conclusion that there are at least two biological species: the Indo-Pacific finless porpoise (Neophocaena phocaenoides) and the...
