Xavier Brunetiere, general secretary at the Reunion town hall, said the surfer’s right foot and his hand were seriously injured, in the attack at Saint Leu, located in a marine reserve on the western side of the island.
The man, whose identity was not released, is aged about 40 and is an experienced surfer, Brunetiere said.
Witnesses said the shark had severed a hand and a foot from the victim, but he made it back to the beach by himself. His life was not in danger, Brunetiere said.
Shark attacks here have been increasing in the last two years, with three surfers killed in the last 13 months.
Sunday’s attack, the third this year, comes just over a fortnight after 22-year-old local Alexandre Rassica was killed by a shark who bit off his leg.
