Cretaceous 'Krakens' Were Apex Predators
Scientists have identified two colossal new species of finned octopuses, dubbed "krakens," that roamed the oceans 100-72 million years ago, reaching an astonishing 7 to 19 meters in length. These ancient giants were powerful apex predators that crushed hard bones, challenging the long-held belief that vertebrates solely dominated prehistoric marine food chains.
