I knew megalodon would be #1 before seeing this
I’m guessing #1 will be Micockedon.
Pliesaurus (spelling) is the scariest in my opinion. For anyone that has PSVR, get Time Travel VR. It’s basically an educational game where you explore the ocean in the prehistoric period and log info about many different sea creatures. It’s not an amazing game, but it’s definitely solid. Seeing the Pliesaurus come after you with it’s giant open mouth and huge eyes is scary as hell.
She says the second guy is 20 feet long yet the guy is like it weighed over 150 tons. either she meant to say meters or thats one fat ass monster lol
I LOVE THE OCEAN!!! I WANNA SWIM NEXT TO A MEGALODON!!!!
you forgot to include my ex in this list
Theres a lot of scientist that are pretty sure that the Megalodon still exist in the deep ocean
The Mosasaurus was the king of the ocean
why is the world so scary and cruel
