Although primary prey type changes between size classes of the stingray and the habitat that it feeds in, the main prey groups are crustaceans, molluscs, polychaetes and hemichordates. Crustaceans and molluscs are the most common prey among other closely related species of stingray.
Stingrays' diet is influenced by both their size and the environment they inhabit.  Crustaceans and mollusks are the most commonly consumed food sources for these species.
