PORTLAND, Maine (AP) — One of the rarest whales on the planet has continued an encouraging trend of population growth in the wake of new efforts to protect the giant animals, according to scientists who study them.

The North Atlantic right whale now numbers an estimated 384 animals, up eight whales from the previous year, according to a report by the North Atlantic Right Whale Consortium released Tuesday. The whales have shown a trend of slow population growth over the past four years and have gained more than 7% of their 2020 population, the consortium said.
