The aim of this study was to morphologically characterize helminth eggs recovered in coproparasitological exams by sedimentation and to analyze their relationship with helminth species recovered during necropsy of juvenile specimens of C. mydas. Four different egg morphotypes were found, identified, and classified as digenetic trematodes of the families Microscaphidiidae, Cladorchiidae, and Spirorchiidae. There was morphological diversity in the size of the eggs measured directly in adult parasites, with sizes ranging from 19.07 to 99.28 μm in length and from 11.35 to 45.66 μm in width. The observation of eggs on coproparasitological exams is important for studying the ecology of sea turtle parasites, since the life cycle of some species is not yet fully understood. Aunque algunos estudios han identificado parásitos en tortugas verdes (Chelonia mydas), poco se sabe sobre la morfología de los huevos de helmintos en las heces de estos animales. El objetivo de este estudio fue caracterizar morfológicamente huevos de helmintos recuperados en exámenes coproparasitológicos por sedimentación y analizar su relación con especies de helmintos recuperados durante la necropsia de ejemplares juveniles de C. mydas. Se encontraron e identificaron 4 morfotipos de huevos distintos, clasificados como trematodos digenéticos de las familias Microscaphidiidae, Cladorchiidae y Spirorchiidae. Hubo diversidad morfológica en el tamaño de los huevos medidos directamente en los parásitos adultos, con tamaños que variaron de 19.07 a 99.28 μm de largo y 11.35 a 45.66 μm de ancho. La observación de huevos en exámenes coproparasitológicos es importante para el estudio de la ecología de los parásitos de las tortugas marinas, ya que el ciclo de vida de algunas especies aún no es completamente entendido.
