САМЫЕ ОГРОМНЫЕ МОРСКИЕ СУЩЕСТВА, КОТОРЫЕ СУЩЕСТВОВАЛИ

The ocean has always produced creatures of unimaginable size. In this video, we'll tell you about the five largest sea giants in the history of life on Earth—from the most ancient to the modern. Shastasaurus was a 21-meter-long torpedo from the Triassic period that hunted without a single tooth. Liopleurodon and its pliosaur relatives were "flying" predators of the Jurassic seas with 1.5-meter-long skulls and 30-centimeter-long teeth. Megalodon was a warm-blooded killer shark that specialized in hunting whales. Basilosaurus, a 25-meter-long serpentine whale with tiny hind legs, is living proof that whales once walked on land. And finally, the blue whale—the largest animal in the 4.5 billion years of life on Earth—living right now, feeding on little-finger-sized crustaceans. Each of these giants pushed the boundaries of what was possible. But each fell when conditions changed. The blue whale is the last giant. And its future depends on us.
