A beluga whale that swam up the River Seine in France appears to be underweight and officials are worried about its health, regional authorities say.
The protected species, usually found in cold Arctic waters, had made its way up the waterway and reached a lock about 70km (44 miles) from Paris.
The whale was first spotted on Tuesday in the river that flows through the French capital to the English Channel, and follows the rare appearance of a killer whale in the Seine just over two months ago.
