Learn more about the whale you took a picture of in Alaska by uploading the photo to happywhale.com. As long as the picture includes a unique marking, like the underside of a humpback’s flukes, Happywhale will identify the individual, show you past sightings, and alert you when future sightings occur.
Launched in 2015, Happywhale at first offered identification only for humpback whales. Collaborators with the site now attempt to identify a wide range of marine mammals, including Dall’s porpoise, sea otters, and Steller sea lions. Photos submitted by users are entered into a database that allows scientists to track marine mammal populations, learn more about migrations, and even estimate the survival rate of marine mammals.
