White sharks (Carcharodon carcharias) ambush their prey from below and even sharks closer to shore like reef sharks are known to chase their prey into smaller crevices before eating them. Yet a small portion of the diets of most sharks still comes from picking apart already dead animals. In a study published May 29 in the journal Frontiers in Fish Science, a team from the University of Hawaiʻi at Mānoa describe an unusual aggregation of sharks coming together to feed on a decaying carcass of an unidentified animal. "To our knowledge, this is the first study to document a feeding aggregation of tiger sharks and oceanic whitetip sharks scavenging concurrently, and peacefully, on a carcass," study co-author Molly Scott said in a statement.

But have you ever wondered what a fight between a hippopotamus and a great white shark might look like? Now, scientists have set the record straight, after using artificial intelligence (AI) to simulate battles between the most terrifying animals on Earth. Somewhat surprisingly, the simulations suggest that a hippo would beat a great white shark - and could even take down a polar bear. However, the ultimate champion of the animal kingdom is the African Elephant, according to researchers from Animal Matchup. In honour of World Animal Day, experts from Animal Match set out to settle the debate - which animal is the strongest?

Sharks and a saltwater crocodile went on a feeding frenzy about a mile off the coast of Western Australia. Sharks and a saltwater crocodile went on a feeding frenzy about a mile off the coast of Western Australia -- and the "rare" event was caught on tape. A drone captured the predators feasting side-by-side on a 16-foot hump-back whale carcass floating near a sandbar off Montgomery Reef. It was the first time sharks and a croc had been documented foraging together. Dr. Austin Gallagher, chief scientist and CEO of Beneath the Waves, a Washington, D.C.-based non-profit organization working to protect the world's oceans, says he's been studying sharks for more than a decade but he'd never seen anything quite like this.
