Mimmo the Dolphin Faces Rising Risks in Venice Lagoon
Mimmo, a wild bottlenose dolphin living in the Venetian Lagoon, has become one of Venice’s most unexpected sights. Near St. Mark’s Basin, he has drawn crowds with energetic leaps and close passes through the water. But what looks like a wonder has also become a warning.
According to The Guardian, researchers monitoring Mimmo say the problem is not the dolphin’s presence. It is the way humans behave around him.

Mimmo is a wild dolphin who swims in the waters of Venice.
Mimmo appears to have adapted to the lagoon. Reports from Marine Connection and AP News describe him as being in good nutritional condition, with regular behavior and active feeding. He has found plenty to eat, including mullet, sea bass, and sea bream.
That has led some people to assume he is doing fine.
He is not.
A wild animal can appear strong and still face immediate danger. Mimmo now swims through one of the busiest aquatic corridors in Venice, where ferries, water buses, taxis, and private boats cross the same waters he uses.

Venice’s lagoon has become dangerous for Mimmo.
Tourism Pressure Has Turned Him Into A Target
As Mimmo’s visibility has grown, so has the pressure around him. Le Monde reported that Venetians described boats approaching him for photos, chasing him across the water, and tourists treating him like an attraction. That kind of behavior may look trivial from a distance, but for a solitary dolphin in an urban lagoon, constant intrusion can bring stress, confusion, and injury.
Researchers and advocates have made the same point again and again: Mimmo does not need spectacle. He needs space.
The Injury Warning Has Already Arrived
The danger is no longer theoretical. AP News reported that experts confirmed superficial lesions likely caused by a boat propeller. Marine Connection also warned that although those wounds were not severe, Mimmo may not be so fortunate next time.
That should end any argument for delay.
Once a wild dolphin becomes famous in a place defined by dense tourism and marine traffic, passive concern is not enough. Officials should impose and enforce safe-distance rules, lower boat speeds in the areas Mimmo frequents, strengthen on-water oversight, and make clear that harassment and risky approach will not be tolerated.

Mimmo appears healthy, but that does not mean he is safe.
Venice Must Choose Protection Over Spectacle
Mimmo did not ask to become part of Venice’s tourist landscape. He is a protected wild animal living inside a human-controlled environment that can injure or kill him at any moment. Venice still has time to act before curiosity becomes catastrophe.
If this dolphin’s story has moved people, that concern should become pressure. Sign the petition and demand real protections for Mimmo now.
