"This is the longest-lived vertebrate on the planet," said Professor Kim Praebel of the University of the North, Norway, who led the research. "We are studying the entire nuclear DNA of the cell to understand why it lives longer than other sharks and vertebrates."

If found, "longevity" genes could help scientists understand the lifespan limits of most vertebrates and what governs average lifespan in other species, including humans.

Greenland shark tissues, bones and DNA could also provide clues about the effects of climate change and environmental pollution.

Greenland sharks are common in the deep waters of the North Atlantic, andScientific name Somniosus microcephalus, belongs to the shark family Somniosidae, has existed on Earth for about 110 million years.
