Over 85% of the world’s Steller sea lions have vanished and no one knows why. Since 1980, the population has plunged from 300,000 to less than 50,000! We’re worried about the sea lions and what their loss means for the ocean ecosystem.

The Vancouver Aquarium has teamed up with researchers at the University of British Columbia in an exciting and ambitious project to find out what’s behind this mysterious disappearance. Steller sea lions at the Aquarium are helping answer critical questions that we can’t solve in the wild.
