Research suggests distinct subspecies of killer whales and common dolphins in Eastern North Pacific.
About Killer Whales and Common Dolphins
While the taxonomic status of killer whale ecotypes (Orcinus orca) and common dolphin subspecies (Delphinus delphis) has long been debated, recent research suggests newly recognized subspecies classifications. Marine mammal researchers at NOAA Fisheries and their colleagues are leading this effort by integrating a variety of survey methods and specialized tools - including genomics, acoustics, and photogrammetry. These methods and results allow researchers to better understand the taxonomy and role of these animals in ocean ecosystems.
