Several orcas played with a boat driven by a San Diego lifeguard, and it was all captured on video.
Ben Lewis and his friend were fishing off the coast of San Diego when they spotted the orcas.
The orcas noticed them too, and they swam right up to the boat and kept up with it at full-speed.
We tried talking to Lewis last night, but he was on duty. We will be staying in touch with him to try to hear about his incredible experience.
For now, you can watch the video here:
