"I've never seen so many dolphins riding on one wave like that. It was a lucky day for me. It all happened so fast, and then they disappeared," Blacklow shared.

This isn't the first time dolphins have been recorded riding the waves. However, researchers are still unsure of the exact reason.

"There hasn't been any outstanding research done to understand the purpose of dolphin surfing. As far as we know, in many populations, dolphins may spend a lot of time socializing and playing," said David Lusseau, professor of marine sustainability at the National Institute of Water Resources, Technical University of Denmark.

"Play takes many forms, from interacting with objects like kelp, human belongings, to other animals. For example, in one population I studied, dolphins would pull on the ropes of fishing cages to submerge buoys, then release them at the bottom and race to the surface. They also played with kelp, holding it on their flippers or noses. These kelp games were sometimes social. Dolphins would pass kelp to each other while others tried to catch it," Lusseau added.

While play is an important part of dolphin behavior, there may be a more practical reason for their surfing. According to Lusseau, dolphins are very good at utilizing their environment to meet their needs, whether for entertainment or serious purposes.

"In some cases, 'surfing' can be understood as dolphins using waves to hunt, hide, or evade. If hunting, dolphins can conceal themselves using the noise and pressure of the waves, thus approaching prey more effectively. Dolphins can also hide in the waves to pursue or get close to other animals they are fighting or playing with. In addition, dolphins can rely on waves to hide, concealing the wave pressure and the sounds they make from other dolphins or predators," he explained.
