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

    There is absolutely no way that all of them went extinct. There has to be atleast one left in the world probably in the mariana trench

    Yeah well, if you had the ability to be everywhere under all four oceans at the same time, you'd probably not make such a rediculous video.

    The Megalodon could still be alive because only 5% of the ocean has been explore so anything could be under there maybe even the Kraken or the Megalodon and their been many sightings of them over the years and this one of the most deepest trench in the world and 70% of the Earth is covered by water and little of the Earth is covered by land so the Megalodon could be alive

    I have a theory: what if Megalodons made babys and then it repeats to this day? So maybe megalodons are steal here. Same for all species that scares me
