No North Atlantic right whales killed in Canadian waters in 2018

Protection measures appear to be working, but the outlook for the whales remain bleak as only 411 are believed to remain worldwide

No North Atlantic right whales were killed in Canadian waters last year - a rare glimmer of hope for officials working to protect one of the world's most endangered species.

While the government protection measures appear to be working, the outlook for the whales remains bleak: only 411 are believed to remain worldwide, with fewer females giving birth than in previous years.
