Snake-like shark from dinosaur era might scare you out of sea

Rarely seen 'living fossil' frilled shark caught off Algarve coast Portuguese trawler catches 'prehistoric shark' during mission to 'minimise commercial fishing'

Scientists from Portugal's Institute for the Sea and Atmosphere (IPMA) have dubbed the catch a "living fossil", after using techniques to identify the animal that indicates the species dates back nearly 80 million years.

The researchers believe that the animal has remained unchanged over the millions of years, and how it managed to survive unchanged when nearly all species were wiped out or forced to evolve to survive is a mystery. The scientists were working on a European Union project to "minimise unwanted catches in commercial fishing" when they came across this "shark from the age of the dinosaurs". The Shark is said to get its name from the frilled arrangement of its 300 teeth.

The male frilled shark (Chlamydoselachus anguineus) measured 1.5 meters (5ft) in length and was caught at a depth of roughly 700 meters (2,300ft) in waters off the resort of Portimao. The gills are frilly with fluffy edges.

Scientists believe it resides off the coast of Australia, Japan and New Zealand. Another study of a Suruga Bay inhabitant showed that frilled sharks may also have the longest gestation period of any living creature, 42 months.

MS Dhoni on criticism: Everybody has views and it should be respected
Agarkar said in a meeting to ESPN Cricinfo, "I figure India should now take a gander at different options, at any rate in T20Is". Imagine any other player in the team getting pushed like Dhoni had been anywhere between No 4 and No 7 positions.

The researchers caught the mysterious creature off the coast of the Algarve, which has a long, snake-like body and 300 teeth.

The frilled shark has a remarkably simple anatomy, probably because of a lack of nutrients in its aquatic environment.

However, unknowingly scientists unearthed one of the most ancient animals to have lived on the surface of this planet. There are a lot of things to that are unknown about this rare and unique frilled shark.

The Portuguese Institute for the Sea and Atmosphere has named it as a "living fossil".
