Question: is livyatan bigger than megalodon?
Answer: After the dinosaurs went extinct, 65 million years ago, the biggest animals on earth were confined to the world's oceans—as witness the 50-foot-long, 50-ton prehistoric sperm whale Leviathan (also known as Livyatan) and the 50-foot-long, 50-ton Megalodon, by far the biggest shark that ever lived.
