The Greenland shark, a massive creature that thrives in sub-Arctic waters, may be the oldest animal in the world, a new study (http://science.sciencemag.org/cgi/doi/10.1126/science.aaf1703) finds.
Researchers estimated that the sharks have an average lifespan of at least 272 years. That’s roughly six decades older than the previous contender for longest-living vertebrate: the bowhead whale.
The study, published Thursday in the journal Science, sheds new light on the little-k**wn Greenland shark (Somniosus microcephalus), which is rarely observed in its natural environment. *

The sharks prefer chilly waters, between 30-50 degrees Fahrenheit, and can swim down to 7,200 feet below the water’s surface. They can also clock in at around 2,220 pounds.* Read more...
