Sea turtles navigate using Earth's magnetic field like a GPS. Scientists found they learn and remember magnetic locations.

Discover how sea turtles navigate the ocean using their internal GPS and learn about their magnetic field perception.

The turtles danced with the most enthusiasm in the tank when they knew they would get food. This was "strong evidence" that turtles can learn the magnetic signatures of "specific geographical areas", the researchers said. Even when tested four months later, the turtles still knew where they should dance.

This week, see what makes loggerhead sea turtles “dance,” track a cosmic “ghost particle,” uncover an ancient basilica, and more.

Loggerhead sea turtles do an excited "turtle dance" when anticipating food. It's adorable, of course, but it has also allowed scientists to understand better how the turtles navigate. Scientists have theorized that sea turtles memorize coordinates to navigate using a magnetic "map.
