The North Atlantic right whale, one of the most endangered cetaceans on the planet, shows a positive trend in population recovery, according to the latest report from the North Atlantic Right Whale Consortium.
In 2025, 384 specimens were counted, eight more than the previous year, consolidating four years of slow but steady growth.
From commercial hunting to scientific monitoring
Historically, this species was intensely hunted, bringing it to the brink of extinction. Although it is now protected by federal laws in the U.S., it still faces serious threats such as:
- Collisions with vessels
- Entanglements in fishing nets
- Forced displacements due to ocean warming
Reproduction and health: keys to recovery
According to Philip Hamilton, a researcher at the Anderson Cabot Center for Ocean Life, the population increase is partly due to new protection policies in Canada, especially in the Gulf of St. Lawrence.
This year, 11 births were recorded, including four first-time mothers and mothers with shorter reproductive intervals, indicating an improvement in the overall health of the species.
“A sustained modest growth can make a difference,” Hamilton stated. “The key is to maintain it.”
Cautious optimism: fewer deaths and injuries
Researcher Heather Pettis, president of the Consortium, highlighted that no deaths or serious injuries were detected during the last year, reinforcing the scientists’ moderate optimism.
“This population can change quickly. But the current data allows us to look to the future with hope,” Pettis noted.
Migrations and habitat: a journey of over 1,600 kilometers
Right whales migrate annually from their breeding grounds in Florida and Georgia to their feeding areas in New England and Canada.
This journey has become riskier due to deviations outside protected areas in search of food.
Physical characteristics and behavior of the North Atlantic right whale
- Size: between 12 and 16.8 meters long, up to 70 tons in weight
- Coloration: dark body with white patches on the belly
- Callosities: rough marks on the head, unique to each individual
- Feeding: filter plankton with their baleen, swimming with their mouths open
- Social behavior: breaching, flipper slapping, and low-frequency vocalizations
Coastal habitat and persistent threats
- Preference for waters near bays and peninsulas
- Main risks: collisions, fishing nets, food scarcity, and injuries
Although the progress is encouraging, experts insist that stricter measures are needed to ensure the long-term survival of this emblematic species. Reproductive health, constant monitoring, and maritime route management are essential to consolidate this recovery.
