Why Megalodon (Definitely) Went Extinct

Loading...
  • Published on: 19 December 2018
  • For more than 10 million years, Megalodon was at the top of its game as the oceans’ apex predator...until 2.6 million years ago, when it went extinct. So, what happened to the largest shark in history?

    As some of you have pointed out, the size comparison we show at 9:36 features a humpback whale instead of a blue whale. That's my fault! The illustration (from a stock photo site) was improperly labeled and we missed the mistake in our review. We spent so much time making sure we had all of the extinct species depicted accurately that we missed the (enormously) obvious error right in front of us. Sorry for the mistake! -Seth

    Only 5% of the ocean has been explored. There's still 95% that's unexplored. You can't say for sure if they're extinct!!!

    NOO this is all wrong.Everyone knows that Megalodons went extinct because people couldn't eat too much fish in hungry shark.

    If artist's reconstructions are anything to go by, the real reason Megalodon went extinct is that it lost the ability to close its mouth 😏

    I don't see how anything that lives in the ocean could go extinct especially a massive shark

    Megalodon was filmed recently by scientists vessel so yeah why it’s definitely still alive...because it’s been seen

  • HoNewerth

    It's a bit hard to believe they went extinct because of scarcity of prey. If whale population really did fall, shouldn't one expect for a species to adapt and start eating things other than whales? I mean, if you're hungry you'll eat virtually anything

    The Megalodon could grow up to 60 feet long. It probably died because it was always so hungry. Imagine eating a bag of Cheetos, and your really hungry. Imagine having to have to count to 10 seconds or sometimes more just to have one... That’s probably how they felt, and the starved.
