Greenland sharks are the longest-living vertebrates known on Earth.   One female shark has been radio-carbon dated at around 400 years old.   These sharks grow at a rate of 1cm each year to reach reproductive maturity at about age 150.   The former vertebrate record-holder was a bowhead whale estimated to be around 200 years old (but still the oldest recorded mammal).   The female shark was likely born in the 17th century.
