Ecology Summary - Sphyrna tiburo
Ecology of Sphyrna tiburo
 
Main Ref. Cortés, E., C.A. Manire and R.E. Hueter, 1996
Remarks Abundant in critical seagrass habitats. Previous study has shown its capacity to consume large amounts of seagrass, up to 62.1% of gut content mass. Recently, captive sharks fed with 13C-labelled seagrass diet showed their ability to successfully assimilate seagrass nutrients, making them omnivores. This is the first shark species to demonstrate omnivorous digestive strategy (Ref. 118574).
