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

• A shark was found in the Caribbean — thousands of miles away from its usual habitat in the Arctic.
• The Greenland shark, which has a lifespan of 250 – 500 years, surprised researchers in Belize.
• "It looked like something that would exist in prehistoric times," said a biologist. 

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.
