Rescue impossible as mass stranding kills 16 pilot whales on remote Sable Island

HALIFAX – A marine animal rescue group has confirmed the stranding of 16 pilot whales on the east side of Nova Scotia’s remote Sable Island. None of the animals survived.

The Marine Animal Response Society said Friday the beached whales were discovered June 10 during a routine survey of North Beach conducted by Zoe Lucas, head of the Sable Island Institute and a longtime resident of the island.

Parks Canada was alerted because the crescent-shaped island, 290 kilometres southeast of Halifax, has been a national park reserve since 2013.

Tonya Wimmer, co-executive director of the animal response society, said her group specializes in rescuing beached marine animals, but the island’s remote location made that kind of mission impossible, adding that some of the pilot whales were already dying by the time Parks Canada staff arrived at the beach.

“The unfortunate reality for Sable Island is that it’s 300 kilometres offshore, which means getting there with all the equipment needed in a timely manner is pretty tricky,” Wimmer said in an interview Friday.

Typically dark black or a greyish colour, pilot whales resemble large, stocky dolphins. In fact, they are members of the dolphin family, as are killer whales. And their most notable feature is their bulbous foreheads. In some areas they are called potheads.

They can be found throughout the North Atlantic and are common off Canada’s East Coast.

While they appear small when compared with orcas, belugas or humpbacks, they are about twice the size of bottlenose dolphins, measuring up to seven metres long and weighing in at four tonnes.

Rescuing beached pilot whales normally requires a large group. Five or six people are typically needed to move just one of them. And they can’t be moved one at a time because the family group must be kept together.

“You can’t do it one by one because they’ll turn around and come back in to be with the rest of the group,” Wimmer said.

Wimmer said mass strandings of pilot whales have been reported around the world for centuries. But questions remain about why they happen.
Strandings can be caused by human activity or when a group strays too close to shore while chasing prey.

“And sometimes they just all end up on a beach. There’s a number of things that could be happening and sometimes we never figure it out.”

Wimmer stressed that if a whale or a dolphin is found stranded onshore, bystanders should not attempt a rescue because the animal could be hurt or the rescuers might be injured by the animal.

“Their tail is their most powerful weapon,” she said. The best course of action is to call for help. The Marine Animal Response Society, for example, has its own toll-free hotline.
