Sydney, June 29, 2012 (AFP) – Scientists were at a loss Friday to explain the mysterious deaths of more than 70 green turtles that have washed up on beaches in northeast Australia over the last week.
Queensland state authorities said 62 of the vulnerable species were confirmed dead and another 10 were spotted floating at sea by a helicopter.
Marty McLaughlin, operations manager at Queensland Parks and Wildlife Services, said the turtles were nourished and had no obvious signs of illness.
“There is no obvious cause of death. We’ve tested for all the normal reasons, like boat strikes and starvation, but that has not occurred,” he told AFP.
