Give Right Whales Room
North Atlantic right whales are on the move along the Atlantic coast of the U.S. If seen, remember that approaching a right whale closer than 500 yards is a violation of federal and state law.
Right Whales in Trouble
North Atlantic right whales are protected under the U.S. Endangered Species Act and the Marine Mammal Protection Act. Scientists estimate there are fewer than 350 individuals remaining, making them one of the rarest marine mammals in the world.
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.
