Little is known about world's longest-living vertebrate, which can live for centuries in the frigid Atlantic ocean from Canada to Norway and off the coast of Scotland.

One shark was discovered to be so old that it it was born in 1624, the year England declared war on Spain and founded it's first Caribbean colony.

The incredibly old monster was discovered by the University of Copenhagen, Denmark.

This means it has lived through the Great Fire of London, The English and American civil wars and both world wars of the last century. How mysterious & elusive 500-year-old ‘invincible’ polar SHARK may hold secret to extending human life | The US Sun (the-sun.com)
