Right Whales in Crisis

The year 2017 was devastating for North Atlantic right whales, which suffered a loss of 17 whales, plus an additional mortality in January 2018--about 4 percent of their population--an alarming number for such a critically endangered species with a population currently estimated at about 450 animals.

In August 2017, NOAA Fisheries declared the increase in right whale mortalities an “Unusual Mortality Event,” which helps the agency direct additional scientific and financial resources to investigating, understanding, and reducing the mortalities in partnership with the Marine Mammal Stranding Network, Canada’s Department of Fisheries and Oceans, and outside experts from the scientific research community. welcomes thoughtful comments and the varied opinions of our readers.
