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 whales can weigh anywhere between 500kg to 3,000kg and some had sunk into the sand where they were stranded.
