16th International Otter Congress, in Lima, Peru

From February 24 to 28, 2025, the Peruvian capital, Lima, served as the venue for the 16th International Otter Congress, a gathering that brought together experts from around the world at the Universidad Científica del Sur (UCSUR). Under the theme “Transforming Research into Policy – United at the Crossroads”, the congress fosteredstrategic discussions focused on strengthening the conservation of the14 otter species.

During the event, the  Giant Otter Project team had the opportunity to share significant advancements in their research and contributions to species conservation. Our collaborator and veterinarian, Greice Gonchoroski, presented the study titled “Evidence of canine pathogens in giant otters (Pteronura brasiliensis): A study from Pantanal wetlands, Brazil”. The study aimed to assess the exposure of free-ranging giant otters to the most widespread viral pathogens in domestic dogs, contributing to a better understanding of the risks these pathogens pose to the health of giant otters in the Pantanal.

Gabriel Brutti, a biologist from our team, also participated with the presentation of his study“The image of the giant otter in the context of the digital platform YouTube”, which explores t how video content published on YouTube influences public perception of the giant otter. This research is crucial for understanding the impact of digital media on species conservation, helping shape how the public views and engages with the cause.

Additionally, João Amaral, a project fellow, presented the study“Wildlife associated with giant otters (Pteronura brasiliensis) in the Brazilian Pantanal”. This research  evaluates how other species use  terrestrial structures created by giant otters – such as dens, latrines, and camps – highlighting the role of these structures in terrestrial ecological interactions and demonstrating the importance of giant otters beyond aquatic environments.

One of the main highlights of the event was the diversity of participants, which promoted a rich exchange of experiences and knowledge. Discussions covered topics ranging from advanced monitoring techniques to innovative strategies for conservation education and communication. The congress format – which included lectures, poster presentations, hands-on workshops, and thematic roundtables –  created an interactive environment conducive to cooperation among researchers, conservationists, and environmental managers.

Peru, as the host country,  could not have been more aligned with the event’s central theme.  The country is home to a unique biodiversity and two emblematic otter species of the Americas: the giant otter (Pteronura brasiliensis) and the marine otter (Lontra felina), both of which are threatened with extinction. This reality underscores the Peru’s importance in developing conservation strategies that can serve as a model for other regions and in the fight for global biodiversity preservation.

Collaboration among researchers from different countries strengthens the international otter conservation network, expanding the impact of the actions needed to protect these species. The exchange of knowledge and international cooperation are essential in addressing challenges such as habitat loss, human-wildlife conflicts, and the need for more effective public policies.

Our participation in the 16th International Otter Congress reaffirms our commitment to otters research and conservation, with a special focus on the giant otter, our target species. During the event, our team was represented through three scientific presentations, and our president had the opportunity to deliverseveral lectures, sharing data from the Giant Otter Project and highlighting regional and global conservation efforts. .

We are excited about the new partnerships and opportunities that emerged  and remain determined in our mission to protect the giant otter and otters worldwide. Together, we are advancing conservation and building a sustainable future for these sentinels of the waters.
