Dinosaur-Era Shark With 300 Teeth Still Swims the Ocean

Dinosaur-Era Shark With 300 Teeth Still Swims the Ocean

Scientists working on the Algarve coast were in for a surprise when they caught a rare frilled shark earlier this week.

Researchers from Portugal's national meteorological, seismic, sea and atmospheric organisation, IPMA, said it was a "true living fossil", because its remains had been unchanged for 80 million years, according to BBC News' translation of a Sic Noticias report.

"The research was originally meant to minimize unwanted catches in commercial fishing", the researchers told SIC Noticisas TV.

However, the team unknowingly unearthed one of the rarest and most ancient animals on the planet. Scientists said that its prehistoric contemporaries like T-rex and triceratops died out long ago, but this frilled shark is still swimming around deep below the surface of the world's ocean.

Scientists from the Institute for the Sea and Atmosphere caught the creature at a depth of 2,300ft near Portugal.

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.

Its name may sound unfitting for a beast that swims the deep seas, but as Mental Floss explains the frilled shark is named after its gills. It has also been speculated that the frilled shark influenced 19th century sailors stories of sea serpents. The gills are frilly with fluffy edges.

The frilled shark's mouth gives an appearance of it being bigger in size than other sharks; however, this is because the mouth stretches to the back of its head instead of ending beneath the skull.

Little is known about the shark other than it has 300 teeth and has a snake-like body. For any further need, you can take notes.
