Scientists have discovered that great white sharks (Carcharodon carcharias) actually live longer than previously thought (up to 23 years or so). Using radiocarbon age estimates, Dr. Hamady and colleagues at Woods Hole Oceanographic Institution determined the animals can live to the ripe-old-age of 70+ years. These findings mean that great white sharks, like humans, may take longer to mature. It also means that overfishing may pose more of a threat to them than previously thought.
