Daily Summary

New research shows white sharks have a larger appetite than originally thought

New research suggests that great white sharks might require much more energy and therefore much more food than previously though. The last study on white shark diet found that a 30kg meal could supply a one ton shark with enough energy for about one and a half months. The new study suggests that this would actually only be enough for 12-15 days. Great white sharks are apex predators so this information will help give scientists a better understanding of ecosystem ecology as a whole.

Environment officials are looking into physical causes, such as temperature, electric conductivity and oxygen.
