Scientists just discovered that Greenland sharks can live for 400 years. It makes them the longest-lived vertebrates known

• We tend to think of vertebrates as living about as long as we do, give or take 50 to 100 years. But Greenland sharks don't even reach maturity until 150 years.

• Scientists used the pulse of carbon-14 produced by nuclear tests in the 1950s to determine the age of Greenland sharks.

• Of the 28 fish scientists dated, the oldest is estimated to be around 400 years old—possibly even up to 500 years old.

• The main reason for Greenland shark record longevity is slow metabolism caused by a cold environment (37 to 41 degrees Fahrenheit).
