A mysterious Arctic shark that can live for 500 years got lost and ended up swimming in the balmy waters of the Caribbean, scientists say [Video]

Biologists were stunned to find a mysterious cold-water shark thousands of miles away from its natural habitat, according to a recent marine study. A Greenland shark — the longest-living vertebrate on Earth — was discovered in the tropical Caribbean Sea.

Researchers were tagging and temporarily catching tiger sharks off the coast of Belize when they encountered the mysterious shark, said a paper recently published in the science journal Marine Biology.

After setting a line in Belize’s protected Glover’s Reef Atoll while monitoring and researching tiger sharks, the biologists returned to find their line had moved several miles away from the coral reef into waters as deep as 2,000 feet.

When they retrieved their scientific catch, they were astonished to find the ancient Greenland shark. One of the researchers, Hector Daniel Martinez, remarked, “It looked very, very old,” emphasizing its deep-sea habitat.
