What Stingrays Really Eat Might Surprise You

A study in Wallis Lake, New South Wales, examined the diets of estuary stingrays and common stingarees.

Stable isotope analysis showed oysters were only a minor food source for both species.

Particulate organic matter provided nearly half of their assimilated nutrition, with crustaceans, fish, and snails making up the rest.

The findings suggest estuary water quality, runoff, vegetation, and aquaculture can affect rays indirectly through the food web base.
