Thousands of tadpoles are on a journey from Cleveland to Puerto Rico as part of an effort to save their critically endangered species.
The traveling tadpoles are Puerto Rican crested toads, and the Cleveland Metroparks Zoo is part of the Species Survival Plan that works to breed the toads and release them back to the wild. The plan is managed by the Association of Zoos & Aquariums.

Different kind of find
Scientists have discovered one of the world's weirdest volcanoes on the seafloor near the tip of Baja, Mexico.
The petite dome about 165 feet tall (50 meters) and 4,000 feet long by 1,640 feet wide (1,200 m by 500 m) lies along the Alarcón Rise, a seafloor-spreading center. Tectonic forces are tearing the Earth's crust apart at the spreading center, creating a long rift where magma oozes toward the surface, cools and forms new ocean crust.

Chance of a lifetime
National Geographic photographer Mike Theiss has always wanted to see the northern lights. So when an assignment took him to Whitehorse, in Canada's Yukon Territory, he rented a car and drove more than 550 miles (885 kilometers) north to the Arctic Circle.
While it usually takes a major solar storm to send the northern lights dancing over the lower parts of Canada and the northern United States, auroras can sometimes be seen in the Arctic Circle even when not visible elsewhere. And sure enough, they made an appearance for Theiss.
