Do you know that the prehistoric shark still exists? If you have no clue of what I am saying, then let me assure you the so called "Frilled Shark" is not a myth. It is well known that the Dinosaurs existed a long time ago, not every prehistoric creature was so lucky to survive up to the present era.
A Japanese fisherman captured a video of a 5.2 feet long Frilled shark, in the year 2007. Giant creature was brought to Awashima Marine Park in Shizuoka but, unfortunately, it survived for only a few hours and died.
It is said to be far older than the Dinosaur.
It has 25 rows and 300 needle-sharp teeth.
