Some of the world's most endangered species are missing. Dozens of Northern Right Whales should be swimming off the coast of Georgia and Florida right now. But this year only five or six showed up, researchers said. That's the most poignant thing of our season.
Scientists hope the cause is something temporary, like the weather.
Whatever the reason for their absence, right whales could be seriously threatened. Fewer than 400 remain. This area off the Atlantic Coast is their only known calving grounds. The season last year produced five. This year there were only two.
