Se analizaron los estómagos de 295 rayas de la especie Urobatis halleri (Urolophus halleri), capturadas en la plataforma continental de Jalisco y Colima (México), en muestreos mensuales de septiembre de 1997 a agosto de 1998. De acuerdo con el índice de importancia relativa, esta especie se alimentó principalmente de invertebrados bentónicos, como los estomatópodos Eurysquilla veleronis y Meiosquilla swetti, anfípodos, el decápodo Processa peruviana y brachiuros portúnidos, y en una menor proporción, de poliquetos y peces.
