Would you ever venture into the ocean if you knew this creature could be lurking beneath you? It's twice the size of a T. rex, its jaws are big enough to crush cars, and it can swallow multiple humans at a time! This ancient beast is called a megalodon shark, and if it had never become extinct, it would have a surprisingly large impact on our lives. How would they change the way we use our oceans? Check out our second channel called “How to Survive“: Correction at 4:33 - Yes, you are correct — the megalodon was indeed a fish and not a mammal. With your support we can make our show better!
