A group of Pacific White Sided Dolphins speed through the water off the coast of Vancouver Island in British Columbia, Canada.

This huge group of Pacific White Sided Dolphins were really stirring up the water as they travelled through Blackfish Sound. They seemed to be on a mission to get somewhere.

They can often be seen riding the bow wake of boats as well as performing stunning acrobatic displays.
