A giant river otter, a species considered extinct in Argentina for nearly 50 years, has been sighted and photographed in a lagoon within El Impenetrable National Park. Researchers believe the animal likely traveled from a population in neighboring Paraguay. The discovery has prompted a new campaign for the protection of the otter, which has begun building a den near the research station.
Facts First
- A giant river otter was sighted in Argentina after being considered extinct there for nearly 50 years.
- The discovery was made inside El Impenetrable National Park by researchers monitoring wildlife during the pandemic.
- The otter is believed to have traveled from Paraguay, a country approximately 140 kilometers (87 miles) north of the park.
- Researchers have launched a protection campaign for the otter, which has begun building a den near their station.
- Giant otters are the world's largest otter species, reaching lengths of nearly 2 meters (6 feet).
What Happened
Researchers quarantined at a ranger station in northern Argentina's El Impenetrable National Park during the COVID-19 pandemic monitored local wildlife. During this period, they sighted a giant river otter (Pteronura brasiliensis) in a lagoon on the Bermejo River. The species was previously thought to be extinct in Argentina for nearly 50 years. The team used kayaks to photograph the otter, which subsequently began building a den near the ranger station.
Why this Matters to You
This rediscovery is a significant event for global biodiversity and conservation efforts. It demonstrates that protected areas like national parks can serve as vital refuges and potential recolonization sites for species thought to be lost from a region. For you, this story highlights a positive environmental development, showing that conservation work can yield tangible, hopeful results. The success of the protection campaign could help ensure the long-term survival of this charismatic species in Argentina.
What's Next
The researchers, including Sofía Heinonen of Rewilding Argentina, have launched a campaign for the protection of the otter. Monitoring of the individual and its new den is likely to continue. The otter's presence may lead to increased scientific study and conservation focus within El Impenetrable National Park to support a potential recovery of the species in Argentina.
