Beached whales may have trailed dead male

A school of 10 whales that washed up on Monday in northern France may have done so voluntarily after the death of the dominant male, an expert said.

Seven of the whales found on the beach in Calais have not survived.

"The group was in the middle of a deep-sea migration toward the Faeroe Islands to reproduce and feed," said Jacky Karpouzopoulos, of the Centre for Marine Mammal Research at La Rochelle.
