Two great white sharks have been spotted in the waters of Newcastle, Australia, prompting officials to shut down the beaches for seven consecutive days.
The sharks, one estimated around three meters long, the other five meters, have been spotted chasing, attacking and feeding on dolphins, whose carcasses now float in the water and wash up on shore.
Newcastle City Council announced that it is “not safe for anyone to be in the water,” and will not re-open the beaches again until at least 24 hours have passed since the last sighting.
