With lifelong bonds, signature whistles, and echolocation, dolphins are more than just smart swimmers. First observed in 2022, World Dolphin Day shines a light on these intelligent marine mammals and the oceans they rely on. The day encourages people to learn about their behavior and the threats they face. Over 40 dolphin species swim our seas, from the Māui dolphin to the Irrawaddy dolphin. They're expert navigators, problem-solvers, and team players. Some even form superpods—temporary gatherings of hundreds or thousands of dolphins moving together offshore.

Off the coast of Marsa Alam in Egypt, pods of spinner dolphins glide through the warm waters of the Red Sea—as seen in today's image. True to their name, they can leap and spin in the air up to seven times in a single jump. Found in tropical waters across the Pacific, Indian, and Atlantic Oceans, they rest during the day in calm bays and hunt offshore at night. But their predictable routines have left them vulnerable to unregulated tourism. Some conservation zones now limit visitor access to allow dolphins to rest undisturbed. The hope? That these creatures continue their spins without interruption.
