This is the third shark attack on humans identified this year. The last attack was on July 15, a young girl had been killed in the Bay of Saint-Paul while she was bathing a few meters off the shore.
A 36-year-old French honeymooner was killed by a shark in May while surfing not far from the island's popular beach of Brisants de Saint-Gilles.
Last year, 78 shark attacks were reported around the world, of which eight were fatal.
