This shark has more than 300 teeth, the length of their body can reach 2 meters, and their movements resemble those of the snakes.
The discovery was made when a team of European Union scientists were searching in the depths of Atlantic Ocean to find a way to "minimize unwanted catches in commercial fishing".
The frilled shark has rarely been encountered alive, and thus poses no danger to humans, although scientists have accidentally cut themselves examining the species teeth.
Researchers were working on a project related to minimizing excessive commercial fishing when they stumbled upon the weird creature. The gills are frilly with fluffy edges. Termed as the pre-historic shark, the creature dates back to 80 million years making it the oldest species on the planet.
Professor Margarida Castro of the University of the Algarve said that the shark got its name from the frilled nature of its teeth which helped it to rapidly engulf its food.

The reason people are not much aware about this freakish creature is because of its rare contact with human as it lives deep down the oceans, off the coasts of Japan, New Zealand and Australia.
The frilled shark has a remarkably simple anatomy, probably because of a lack of nutrients in its aquatic environment. There are a lot of things to that are unknown about this rare and unique frilled shark. Scientists, therefore, have not been able to study it in research laboratories and there is also little footage of the primeval shark in its natural habitat.
