For months now, Venice has been charmed by an unusual tourist: Mimmo, the bottlenose dolphin, who’s been swimming and doing flips in the city’s canals for months.

City officials hope to see him move to open waters, though, after confirming that he’s likely been injured by a boat propeller in a city lagoon.

After a failed operation over the weekend to try to nudge Mimmo into safe waters, officials say they don’t plan any immediate action, and are hoping that colder temperatures will lure him out of the lagoon toward warmer waters.
