The North Atlantic right whale population in Canada has stabilized, with no reported deaths since 2019, but there are still concerns about entanglements and low birth rates.

North Pacific right whales, once numbering in the tens of thousands, swam throughout the Bering Sea until they were nearly wiped out by commercial hunters. Now the Eastern North Pacific right whale population is estimated to total about 30 individuals, and its habitat is believed to be concentrated in the southeastern corner of the Bering Sea.

Two more calves have been spotted off the coast of Amelia Island in Florida, increasing the total number of calves seen this season to 11, according to the National Oceanic and Atmospheric Administration.

An endangered species of whale that lives off the East Coast is having its best season for new babies in several years.

Waters off the coast of Maine are warming faster than 99 percent of the world's oceans. That's forcing whales northward in pursuit of prey, threatening some of their already dwindling populations.
