The diet of S. tiburo is dominated by crustaceans, consisting mostly of blue crabs, but also it feeds upon shrimp, mollusks, and small fishes. Seagrasses were also found in stomach contents.
It was found that stomach content weight of females was higher than that of males, probably because females, due to reproduction, have a higher energy budget. They need to feed more in order to store energy for when they reproduce (Cortes , Manire, and Hueter,1996).
