On December 3, 2014, at approximately 19:00 hr, four young-of-the-year <em>S. lewini</em> were caught with hand line in Wafer Bay, Isla del Coco, Costa Rica (5°32’42.4” N - 87°03’45.3” W). A total of three males (total length (TL): 73, 73, 76 cm) and one female (TL: 75 cm) were recorded. The presence of these individuals at Isla del Coco suggests that a pregnant female gave birth in or near Wafer Bay, which may be a nursery ground for <em>S. lewini</em>. We recommend further study to evaluate the presence and movements of young-of-the-year and juvenile <em>S. lewini</em> in Wafer Bay to determine if this was an isolated incident or if the bay is a nursery ground for <em>S. lewini</em>.</p><div> </div>}, number={S1}, journal={Revista de Biología Tropical}, author={Zanella, Ilena and López-Garro, Andrés and McComb-Kobza, D.
