World Dolphin Day Sep 12, 2025

World Dolphin Day

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. 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.
