60 out of 80 children in the flock of pepper whales have died of being stranded in Marion Bay, southeast Tasmania, Australia.
According to Radio Australia, the bodies of these fish were discovered by a local fisherman early on.
Rescue workers are working urgently to save the lives of several exhausted children.
According to Liz Wren, a Tasmanian National Park and Wildlife Service spokesman, nearly 70 whales have been worn out early in the morning, but because the area is difficult to reach by road, when the authorities along with volunteers came to the place, only a few survived.
"We saved 10 children. The rest were dead," Wren said. "To make sure the whales we brought back to the ocean were not stranded again, we sent the boat to stay there until late at night to keep them away."

Pilot whales - which can be up to 6 meters long when fully grown - often run out of flocks, a phenomenon that remains a mystery to scientists.
The scientific community has made some theories about the cause of this strange phenomenon. "One of them is that whales often go over the coast of rough seas. When in danger, they often signal to call other members in the herd," said Wren.
Tasmania's coast is rarely peaceful as one of the world's highest rates of stranded whales. According to local authorities, about 2,800 pepper whales and 500 dolphin dolphins were aground here as of 2003.
