Greenland Shark
The Greenland shark (Somniosus microcephalus), also known as the Grey shark, Gurry shark or Ealussuaq, has gotten a lot of publicity lately. This is because recently a Greenland shark was found that was estimated to be about 400 years old! That is 200 years older than their average lifespan and it makes the Greenland shark the longest living vertebrate on earth. Moreover Greenland sharks are incredibly large; they can grow up to about 6.5 meters and they weigh about 900 kilos
