Scientists just discovered the oldest known vertebrate — and it could be nearly 400 years old. A recent study of Greenland sharks published in the journal Science revealed two of the 28 sharks examined to be 335 and 392 years old, respectively. These sharks' ages are nearly double that of the bowhead whale previously estimated to be the oldest vertebrate, at 211 years old.

Not much is known about the new record holders dwelling in the North Atlantic Ocean. Researchers estimate Greenland sharks, which can be as long as five meters, grow a mere centimeter annually. It isn't until age 150 that the sharks reach sexual maturity.
