Shark Dating Back to 800 Million Years Found Swimming Offcoast of Portugal


We all love oceans but it is quite uncommon to come across prehistoric creatures swimming across the oceans, on the other hand, it was a lucky day for the Portuguese Scientists who caught a shark aboard belonging to the age of dinosaurs from the Algarve cast. The frilled shark - Chlamydoselachus anguineus - is often referred to as a "living fossil". While it has a long slim snake-like body it has a unusual circular arrangement of 300 teeth.

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. Termed as the pre-historic shark, the creature dates back to 80 million years making it the oldest species on the planet. The shark has six pair of gills which is frilly edges.

Professor Margarida Castro of the University of the Algarve told news website Sic Noticias that the shark has a unique mouth shape and gets its name from the frilled arrangement of its 300 teeth.

The frilled shark possesses dorsal, pelvic and anal fins allowing it to lunge at its prey in a similar technique used by terrestrial snakes.

The shark was caught at a depth of 701 meters near the resort of Portimao. The scientists further said that the rare and ancient creature might have inspired 19th-century tales of "sea serpents".

The frilled shark is found across the Atlantic, including off the coast of Norway and in the waters of Scotland, Galicia in Spain, the Azores, Madeira and the Canary Islands, as well as in the Indian and Pacific Oceans, namely off Japan, Australia and New Zealand. Scientists should take advantage of getting the shark as a living fossil and study in details about it and also they should try to find out more of them in the unexplored regions of the sea.
