80 Million Years Old,,,,, and still Alive!?

It's a Damn Ugly Fish, that is for sure, they have found one alive and well, and this ugly thing hasn't changed in 80 million years.

PREHISTORIC, DINOSAUR-ERA SHARK WITH INSANE TEETH FOUND SWIMMING OFF COAST OF PORTUGAL

A living Fossil they said.

The rare frilled shark is considered a “living fossil,” because evidence of its existence dates back to at least 80 million years ago. This summer, researchers found one alive and thriving off the coast of Portugal, adding yet more clues about the resilience of this ancient sea creature.

So it's classified as part of the Shark Family.

Scientists believe the frilled shark has remained the same, both inside and out, since the Cretaceous Period, when the Tyrannosaurus Rex and Triceratops still roamed the planet.
The creature, known by scientists as Chlamydoselachus anguineus, is incredibly simple and unevolved, most likely due to the lack of nutrients found in its deep-sea dwellings.
 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.

This deep sea dweller is usually found between 390 and 4,200 feet below the surface, which is why it’s rarely seen and wasn’t even discovered before the 19th century (despite being around long before humans).
