A video is circulate onTwitterwith claims that the animate being shown is 80 million years sometime – while this is obviously not true , let ’s give them the benefit of the doubt as to how they reached this ending .
The telecasting isfrom 2007and was film at Awashima Marine Park In Japan . It ’s extort up an impressive 8.7 million views since it was send on October 14 .
The species in the television is a frilled shark ( Chlamydoselachus anguineus ) , an extremely rarefied recondite - sea beastie that typically lives at depths between 120 - 1,280 meters ( 394 - 4,199 infantry ) .

The shark ’s name refers to its row of six frilled branchia slits . This species can turn to 2 meters ( 7 ft ) long and hasaround 300trident - shaped tooth over 25 rows . This species has a wide but patchy distribution , popping up in places such as the coast of Norway , Portugal , and evenVictoria , Australia .
With a body like an eel and that fearsome rima oris , it does calculate like an ancient creature from the inscrutable . Often chip in the byname of “ animation fossils ” , researchers remember that the specie ( notthe individual shown in the viral video ) is one of the most ancient surviving , having not changed much in the last 100 million years of evolutionary history .
The frilled shark is in its own family , the Chlamydoselachidae , believed to be the oldest living fellowship of selachian ( shark , skate , and rays ) .
Frilled shark belong to to the order Hexanchiformes that live in the sentence of the Cretaceous . Fossils of this specie have been determine that date back 80 million years , which think of they were swimming around in the sea at the same time as Triceratops were roaming around on land .
However , the lifespan of an individual is remember to be around 25 old age , not 80 million . If you ’re still desperate for an impressive shark lifespan fact , Greenland sharksare the existence ’s longest - live vertebrates , with some living around 500 years .
