This study provides the first documented evidence of leatherjackets (<em>Oligoplites</em> sp.) engaging in cleaning symbiosis with a Spinetail devil ray (<em>Mobula mobular</em>) off the coast of Ilhabela, southeastern Brazil. Drone footage captured on May 12 and May 24, 2024, revealed leatherjackets scraping their bodies against the devil ray's dorsal surface, targeting their heads and lateral surfaces, aligning with incidental cleaning behavior. This novel interspecies interaction occurred during an upwelling bloom, attracting numerous marine species to the area. Potential ecological implications of declining elasmobranch populations due to climate change and human activities are also noted.</p> Rachel Ann Hauser-Davis Salvatore Siciliano Arlaine Francisco Aurea Ciott Rafael Mesquita Ferreira Júlio Cardoso André Luis S.
