Photos of giant whale sharks snapped by vacationing scuba divers and snorkelers are helping scientists track the elusive marine creatures across the oceans.

And the same technique may soon also help researchers track polar bears in Canada, giant Eurasian trout in Mongolia, and ocean sunfish in the Galápagos Islands.
