Venice’s Playful Dolphin Visitor Raises Safety Concerns
A wild dolphin nicknamed Mimmo has become an unexpected tourist attraction in Venice, delighting visitors with acrobatic flips for months, but marine experts now worry his proximity to humans has put him in danger.
Wildlife officials attempted to guide the bottlenose dolphin away from the heavily trafficked St. Mark’s Basin on Saturday using low-intensity acoustic devices. The intervention worked only briefly before Mimmo returned within an hour, reinforcing concerns about his safety.
“It’s very worrying because it’s a hot spot with lots of boat traffic,” said Guido Pietroluongo, a veterinarian at the University of Padua’s emergency response team for stranded dolphins, whales and porpoises (CERT). The basin, situated in front of St. Mark’s Square and connecting to both the Giudecca and Grand Canals, sees constant ferry, water taxi, and private boat traffic daily.
During Saturday’s relocation attempt, experts confirmed Mimmo had suffered superficial lesions likely caused by a boat propeller. While the wounds are expected to heal fully, they represent the first documented injuries since his arrival and have heightened concerns for his welfare.
Authorities aren’t planning immediate intervention, instead hoping that cooling seasonal temperatures might naturally draw both Mimmo and his fish prey toward warmer waters outside the lagoon, Pietroluongo explained.
Mimmo was first spotted in the Venetian lagoon on July 23 and likely followed schools of fish into the brackish waters that are separated from the open sea by barrier islands. His nickname comes from the sailing instructor who initially spotted him near the fishing town of Chioggia in the Venetian lagoon.
Marine biologists have identified Mimmo as a “social loner,” typically a young male dolphin that separates from its pod either for food or social reasons and then becomes comfortable with human environments. “Around 100 cases have been documented around the world in which these animals are absolutely at ease and remain healthy despite not interacting with their peers,” said Sandro Mazzariol, another CERT veterinarian, in a Facebook video.
While dolphin sightings in Venice are uncommon, they aren’t unprecedented. In February 2021, a pair of striped dolphins entered the lagoon but were quickly guided back to open waters using acoustic devices and never returned. Mimmo’s case differs significantly, as he has established the area as his territory and shows no inclination to leave.
Despite the risks, scientists monitoring Mimmo report that he appears to be in good health and nutrition. He has been feasting on local fish including mullet, sea bass and sea bream—a diet befitting any Venetian tourist. His playful behavior, including his crowd-pleasing aerial flips, is considered normal for his species.
The University of Padua team conducts weekly check-ups on the marine mammal and receives regular updates from citizens who share sightings, photos, and videos. However, Mimmo’s growing fame is part of the problem.
“The dolphin has become an attraction. Boats stopping to watch him can stress the animal,” Pietroluongo warned.
Italian authorities have issued warnings that feeding or interacting with Mimmo constitutes a criminal offense. Dolphins are protected under Italian law, European Union regulations, and international conservation agreements. Despite these protections, the challenge remains balancing public fascination with the animal’s welfare.
As tourism in Venice continues year-round, officials worry the increasing attention from boats specifically seeking out Mimmo could lead to more injuries or stress. For now, the team continues to monitor his condition while hoping natural factors will eventually guide him to safer waters.

This is a concerning situation. While Mimmo’s acrobatic displays are delighting tourists, his proximity to heavy boat traffic puts him at serious risk of injury or worse. Wildlife officials need to find a safe way to guide him to calmer waters for his own protection.
Agreed. The safety of the dolphin should be the top priority here. Relocation efforts seem necessary to get Mimmo away from the congested canals before he sustains any more injuries.
This is a tricky situation. On one hand, Mimmo has become a beloved local attraction, drawing tourists and delight. But the experts are right to be worried – the boat traffic in that basin is simply too hazardous for a wild dolphin. I hope they can find a humane way to guide him to safer waters.
It’s a shame that Mimmo’s playful behavior is putting him in such peril. The experts are right to be concerned – those busy canals pose a serious threat to the dolphin’s safety. I hope they can devise a relocation plan that keeps Mimmo out of harm’s way without disrupting his natural behaviors too much.
Agreed, the priority has to be Mimmo’s wellbeing. While his antics may be entertaining for tourists, the risks from the heavy boat traffic are simply too high. A successful relocation to a protected area would be the best outcome, even if it means losing this unique attraction.
This is a delicate situation. Mimmo has clearly captured the hearts of the Venetian people, but the experts are right to be concerned about the risks he faces in that busy basin. I hope the wildlife officials can find a humane way to guide him to a safer location without disrupting his natural behaviors too much.
It’s wonderful that Venice has this special dolphin visitor, but the welfare concerns are valid. The basin’s heavy boat traffic is simply too dangerous for Mimmo in the long run. I hope the experts can devise a plan to gently coax him to a safer, quieter location.
Absolutely. Mimmo’s safety has to come first. While his acrobatics are captivating, the risk of serious harm from the boat traffic is too high. A successful relocation to a more protected area would be the best outcome for this unique dolphin.
