The great white shark is the world's largest predatory fish, growing up to 6.4 meters long and weighing over 3,000 kilograms. They have over 300 triangular teeth arranged in rows that are continuously replaced, and they prey on fish, seals, and sea lions. Great white sharks are apex predators with orcas as their only natural enemy, though orcas have learned to paralyze and drown them. They pose the greatest threat to humans of any shark with numerous unprovoked fatal attacks.
