"There has never been such a high number," said Willy Daubin, a member of the National Center for Scientific Research at La Rochelle University. "In just three months, we've surpassed last year's record since 2017, and even that was the highest in 40 years."

Autopsies on the animals were reported to have resulted in significant mutilations.
