Stomach contents and dietary overlap of three round stingray species (Urobatis halleri, Urotrygon munda, and Urotrygon rogersi) captured off the central Pacific coast of Mexico were analyzed during the two main hydroclimatic periods (T1 and T2) that characterize the environmental variability in the area.

In general, the diets were mainly composed of benthic microcrustaceans (caridean shrimps) and to a lesser extent ...
