1,000 dolphins swim beside ferry off Gulf Islands

Passengers aboard a BC Ferries vessel were treated to a rare sight on Friday, as a pod of about 1,000 Pacific white-sided dolphins swam next to the boat for several minutes.

Though this species of dolphin is known for forming large pods, it's unusual that such a large pod was spotted in the Strait of Georgia, rather than in more open waters, such as on the west coast of Vancouver Island.
