A pod of Pacific white-sided dolphins had been milling about in Drew Harbour, Quadra Island for much of the day, alternating between slow, leisurely circling and faster sprints. Towards the end of the afternoon, a signal went out through the pod and the dolphins began ramping up their activity levels. A few individuals breached, and then the pod began an accelerated race around the edge of the harbour with many of the dolphins exploding completely out of the water, as seen in this image. I was on shore at the water's edge, where I had been watching the dolphins for the previous 5 hours. I have never seen behavior quite like this before and couldn't help laughing at how incredible the experience had been once it was over.
