Dozens of pilot whales (or black dolphins), a cetacean that can reach up to six meters in length, have washed ashore in the southwestern tip of Australia.

The total number of black dolphins stranded in Tobey Cove, south of Perth, may be as high as 160, and their chances of survival are considered slim, local authorities said today.

Twenty-six of them were already dead when they were found, according to the Western Australian state Parks and Wildlife Service, which rushed “conservation workers, marine scientists and veterinarians” to the area.

The staff sent there will try to pull some of the cetaceans out into the open, but “euthanasia of the cetaceans that protrude appears to be generally the solution” most appropriate to save them from prolonged suffering, the Service underlines.

More and more whales are found that have washed up en masse on coasts in the world, while the causes of this phenomenon have not been scientifically ascertained to date.

In July dozens of black dolphins died after stranding on the Cheynes coast, about 400 kilometers east of Tobey Cove.
