What If Megalodon Sharks Never Went Extinct?
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?

Correction at 4:33 – Yes, you are correct â the megalodon was indeed a fish and not a mammal.

At 1:54 the video states that Megladons were "warm water mammals" which is incorrect – they weren't mammals but predatory fish

Jurassic Park and Jurassic World taught us that it was a bad idea to bring old species back.
TAKE THAT LESSON

People having theory saying it never actually went extinct

Yeah I think megalodons would be less likely to attack individual swimmers and more likely to attack large groups of swimmers and also boats due to their size. Navies would spend more time escorting ships to fight off megalodons in a similar way to how they were used in WW2 to fend off submarines

If it's still around it's going to be in very small numbers confined to a certain region of the Pacific Ocean. Take for example the California Condor; its population is confined to the Pacific coast of the United States. That bird used to scavenge the carcasses of the mega-ungulates till those beasts went extinct. Condors used to be everywhere now it's limited to feeding off marine mammal corcasses.

I am so glad it is extinctâsupposedly. I hope it is extinct and it stays extinct forever. It was nothing but a huge terrorizer.

why would it hide in the ocean if it's the number 1 predator.
