The Greenland shark is now the longest living vertebrate after scientists found one that was 400-years old.

A study of the animals found they live for centuries - and only grow about 1cm a year.

The shark in question would have been a youngester during the Great Fire of London, reached sexual maturity 100 years before the famine and reached adulthood around the time that the American revolution kicked off.

It's not the world's oldest animal though - that title belongs to a 507 year old clam called Ming.

Other long-living creatures include the Bowhead Whale (approx. 200 years), the Galapagos Giant Turtle (approx. 150 years), the long-finned eel (recorded to live past 100 years) and the 'Turritopsis Dohrnii', a type of jellyfish that has, in a way, developed a sort of immortality through asexual breeding and a regenerative process known as ‘transdifferentiation’.
