World Dolphin Day Sep. 12, 2025

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 behaviour 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.
