HALIFAX — A marine animal rescue group has confirmed the stranding of 16 pilot whales on the north shore of Nova Scotia’s remote Sable Island.

None of the animals survived.

The Marine Animal Response Society posted on Facebook Thursday saying the beached whales were discovered June 10 during a routine survey and Parks Canada was alerted.

When Parks Canada staff arrived at the scene, some of the small cetaceans had already died, and it became clear that a rescue attempt would not be possible, given the island’s remote location and the lack of resources on the island.

Tonya Wimmer, founder of the society, says Parks Canada personnel documented details about each whale and collected samples for further research.

Wimmer says mass strandings of pilot whales have been reported across the world for centuries, but questions remain about why they happen.
