Urolophus jamaicensis, the yellow stingray, is a common elasmobranch found on and around the coral reefs off Florida's southeastern coast. Its diet consists of polychaetes, crustaceans, nemerteans, sipunculids, nematodes, and chaetognaths with polychaetes and crustaceans comprising almost 67% of the stomach contents by volume. There does not appear to be any diet preference between the male and females stingrays. The seasonal changes in diet preference are limited to an increase in the proportion of polychaetes found in the stomach during spring when compared to fall.
