Marine experts have given up hope of rescuing 157 false killer whales that stranded on a remote Australian beach.

After 157 false killer whales were stranded on a Tasmanian beach, experts said only 90 have survived. Following a few failed "refloating" attempts to return the whales to the sea, the remaining survivors are expected to be euthanized.

Department liaison officer Brendon Clark said the stranding was the first by false killer whales in Tasmania in since 1974. That was a pod of more than 160 whales that landed on a beach near Stanley on the northwest coast. Strandings in Tasmania are usually pilot whales.

Over 150 animals, thought to be false killer whales, have stranded themselves in Tasmania. It is unlikely that any will survive the ordeal.

More than 150 false killer whales have been stranded on an isolated beach in the Australian state of Tasmania, with rescue crews trying to save the majority of the large dolphins that survived the ordeal,

More Than 150 False Killer Whales Stranded In Tasmania. More than 150 false killer whales beached themselves during a mass stranding near Arthur River in Tasmania, Australia on Monday and Tuesday. Australian authorities are euthanising about 90 of the whales which survived the stranding as conditions have made it impossible to save the stricken cetaceans.

The animals are part of a pod of 157 whales that beached near Arthur River, a township in Tasmania. What caused them to beach remains unclear.
