Scientists made a remarkable discovery off the coast of Portugal, as we reported recently, finding a rare frilled shark that has a terrifying appearance.
The existence of this sea predator dates back to 80 million years.
This time, however, scientists have come across an exceptionally rare find: a living fossil.
According to the scientists, the species is said to have remained unevolved since the Cretaceous Period, when the Tyrannosaurus Rex and Triceratops roamed the planet.
The shark has a long, slim and a body similar to a snake's.
Scientists suggest that the lack of nutrients in deep aquatic environments contributed to the unchanged appearance of the sea creature. The interesting thing was that the prehistoric frilled shark was caught alive and not in the form of fossils.
A Japanese study of the shark found in Suruga Bay, Japan, revealed that its diet is 61 percent cephalopods-the class to which squids and octopus belong. The shark was first discovered in the 19th century despite how long that it has been around terrorizing the depths of the ocean.
The shark in question measured around five feet in length, but reports indicate that it can grow to well over six feet, bigger than most grown humans.
It was believed that early sailor stories about sea serpents are inspired by the sightings of the frilled shark and its snake-like movements.
As if you needed another reason to never step foot in the ocean ever again, here comes the frill shark to haunt your dreams.
Many Twitter users considered the shark much ado about nothing since it isn't a previously unknown species, just a rarely caught one.
What's the chance our technology will keep our species going for 80 million years?
