Most of the 500 whales stranded ( 搁浅 ) off Tasmania have now died. Dozens more stricken
whales have been found in Australia’s largest ever mass stranding. The estimated total now stands at
around 500, with the majority of that number dead and a tenth rescued by authorities on the Island
state of Tasmania. Experts believe all of the animals would have been part of one large group. Offi cials
began working to rescue survivors among an estimated 270 whales found on Monday on a beach and
two sandbars near the remote coastal town of Strahan. Then another 200 whales were spotted from a
helicopter on Wednesday less than 10 kilometres (six miles) to the south. All 200 had been confi rmed
dead by late afternoon. They were among the 380 whales that have died overall, with estimates from
earlier today suggesting that 30 that were alive but stranded and 50 had been rescued since Tuesday,
Mr. Deka, Wildlife Service manager explained. He added, “We’ll continue to work to free as many of
the animals as we can. We’ll continue working as long as there are live animals.”
It is not known what caused the animals to run aground. While stranding events are not unheard
of, they are very rare in such large numbers. About 30 whales in the original stranding were moved
from the sandbars to open ocean on Tuesday, but several got stranded again. About a third of the fi rst
group had died by Monday evening.
Australia’s largest mass stranding had previously been 320 pilot whales near the Western
Australian town of Dunsborough in 1996. This week’s incident is the fi rst involving more than 500
whales in Tasmania since 2009. Marine Conservation Programme wildlife biologist Kris Carlyon said
the latest mass stranding was the biggest in Australia in terms of numbers of the stranded and died.
Marine scientist Vanessa Pirotta said there were a number of potential reasons why whales
might become beached, includ
