The reappearance of Changuita, a sea otter reintroduced in Chile in 2017, on the coasts of Viña del Mar in April 2026, has generated great excitement among biologists.
Although genetic confirmation is awaited, the observed characteristics, such as its size, behavior, and the peculiar habit of biting its tail, suggest that it could be this very specimen.
This sighting offers an opportunity to assess the effectiveness of wildlife rehabilitation programs.
The discovery came by chance, like many urban fauna stories, through a phone call. Javier Trivelli, co-founder of the Fundación Lontra, was alerted about an otter appearing inside a building biting its tail, a behavior linked to animals that have been in captivity.
The animal’s confident behavior towards Trivelli suggested it was Changuita, but the genetic verification process is still ongoing.
Otter Conservation
Rumors about the sighting of offspring in 2024 and 2025, if confirmed, would indicate significant progress in the survival and reproduction of otters in the wild. This would be a milestone for science and conservation, demonstrating that rehabilitation has a real impact.
The chungungo, also known as the sea otter, is a species that inhabits the Pacific coasts, from Peru to southern Chile. These solitary mammals depend on quiet coastal areas and hidden dens to survive.
In Chile, the species is classified as “Endangered” due to habitat loss and the introduction of invasive species.
The challenges for the survival of the chungungo are numerous. Between 2009 and 2022, 58 otter deaths were reported in Chile, with only 29% attributed to human causes such as dog attacks and conflicts with fisheries. These data underscore the need for preventive rather than reactive measures.
Changuita’s return highlights the importance of adjustments in reintroduction programs. For example, it was discovered that otters need access to freshwater, a detail that can improve future methodologies.
The case of Changuita is already driving the creation of the first otter rehabilitation center in Chile, which could take years to achieve.
Threats to the chungungo include coastal urbanization, noise, and pollution. The recent sighting in Viña del Mar shows how human presence can limit the safety of these animals.
It is crucial to confirm the identity of Changuita and monitor its environment to ensure it remains safe from any human danger.
Ultimately, this event reminds us of the fragility of species inhabiting environments increasingly invaded by humans. The community can support by keeping their distance, ensuring their dogs are leashed, and avoiding feeding wild animals.
The possible confirmation that Changuita has survived is a sign of resilience, but also a warning about the need to better protect these creatures. The assessment of the chungungo on the Red List of the IUCN is already available on their website.
