| 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). |
