Resumen
Reportamos la primera evidencia documentada de depredación de invertebrados por parte del grisón (Galictis vittata), basada en registros de cámaras trampa obtenidos de un collpa en el sureste del Perú. Se registraron dos individuos adultos capturando y consumiendo grandes arácnidos, probablemente amblipígidos (Amblypygi), extraídos de una cavidad natural. Uno de los individuos removió y descartó visiblemente parte de la presa antes de ingerirla, lo que sugiere un manejo selectivo destinado a reducir el riesgo asociado con estructuras defensivas. Estas observaciones amplían el conocimiento sobre el comportamiento de forrajeo centrado en cavidades de G. vittata e indican que los amblipígidos podrían constituir un ítem presa subreportado pero regular en hábitats tropicales.
