In a remarkable discovery, biologists in Brazil have confirmed that a jaguar swam 2.3 kilometers across an artificial reservoir, setting a new record for the species. The previous record, established in 1932, was only 200 meters. The male jaguar was first photographed in May 2020 and later captured on camera in August 2024, showing no signs of exhaustion after the swim. Researchers suggest that while the jaguar may have used a small island as a resting point, the swim itself is a natural behavior rather than a response to danger. This documentation provides rare evidence of jaguars' swimming capabilities and their ability to traverse large bodies of water, enhancing conservationists' understanding of their movement patterns.
