“I think every stranding is unique to the species and the situation. With pilot whales,their strong family bonds may be a contributor to mass strandings,” she said.

“If one animal is sick,or they have navigational issues,they will strand together.”

Wellard said there was only a short window to intervene after the whales stranded,and the longer they spent on the sand,the lower their chance of survival.

WA Premier Roger Cook said the situation had evolved over Tuesday night,despite the best efforts of Parks and Wildlife staff.

“I’d like to acknowledge and thank the hardworking Parks and Wildlife staff who have worked through a very cold night and tough conditions to help these stranded whales,” he said.

“I am advised they now have enough staff and registered volunteers,and the best way to help is for members of the public to stay away from Cheynes Beach today.”
