60 whales die in Australian mass stranding.
Pilot whales, which can grow up to six metres (20 foot) long, frequently beach themselves in a phenomenon that remains a mystery to scientists.
1) One of them may stray too close to the shore in rough seas. Then the distress signal it sends out attracts other members of the pod.
2) It might be something to do with the magnetic fields that they use to navigate.
3) Armageddon?
