Marine biologists were planning the rescue of around 270 whales stranded on a sandbar off the remote west coast of the Australian island of Tasmania on Monday.
Government scientists said it appeared that at least 25 of the animals, believed to be pilot whales, had already died. Pilot whales are a species of oceanic dolphin that grows seven metres long and can weigh up to three tonnes.

“While strandings are not uncommon in Tasmania, and while strandings of this scale aren’t [unprecedented], we certainly haven’t had one for at least 10 years,” Nic Deka, a regional manager for Tasmania Parks and Wildlife Service, said.
Tasmania’s Department of Primary Industries, Parks, Water and Environment said the whales were stranded in three groups in shallow water at Macquarie Heads, some 200 kilometres north-west of the state capital Hobart.
Rescuers with specialised equipment arrived at the site on Monday afternoon to assess the situation. They were expected to regroup on the shore as it grew dark to discuss a rescue strategy.
Officials usually respond to reports of strandings of dolphins and whales in Tasmania once every two or three weeks, on average.
Government scientists had first thought the mass stranding involved about 70 whales when it was viewed from the air, but a closer inspection revealed the larger number.
The last mass stranding off the coast of Tasmania was in 2009, when around 200 whales beached themselves. In 2018, more than 100 pilot whales died after beaching themselves off the coast of New Zealand.
It is not known why whales, which travel together in pods, sometimes beach themselves but they are known to follow a leader, as well as gather around an injured or distressed whale.
“Their social groups and strong bonding between the groups causes often all of them to strand,” Olaf Meynecke, a whale researcher and Project Manager of whales and climate at Griffith University, told Reuters.
