"Sharks that live in deep, cold water could be much older - well over 100," Naylor said. Technologies like satellite tracking are revealing more about great whites and their lifestyles, and scientists may yet discover that 50-something giants like Deep Blue are not so rare after all. Great whites are especially difficult to raise and study in captivity, and as with any big marine animal, observing their habits in the ocean depths is challenging and often dangerous, Naylor added. "There's a lot we still don't know," said Gavin Naylor, a biology professor at the College of Charleston. Glimpses of exceptionally large great whites like Deep Blue can help to shed light on the many unknowns of these elusive creatures. Select from premium Deep Blue Great White Shark of the highest quality. blacktail reef shark, carcharhinus amblyrhynchos (bleeker, 1856). The shark went viral the next year after it was filmed in waters near Mexico and has had its own Twitter account. In 2014, the Discovery TV series Shark Week declared the 20-foot-long Deep Blue one of the biggest great whites ever caught on camera. "The more big females like Deep Blue that we have in the population, the better off the white shark population will be," Curtis told Live Science.

And bigger sharks are more likely to produce big litters, making larger females important from a conservation standpoint. The number of young a shark births can vary, but litters with as many as 10 pups have been documented, said Tobey Curtis of the National Marine Fisheries Service. Shark Files: Largest Shark Ever Filmed Caught On Video Skomal's study hints that there may be much older sharks than Deep Blue out there, and they could be even bigger.Īfter reaching maturity, white sharks' growth slows - but it doesn't stop. A 2014 feature on Deep Blue created by Discovery said the shark is the largest great white ever filmed, measuring more than 20 feet and believed to be at least 50 years old. Padilla estimated that Deep Blue was about 50 years old, based on her size. That study also showed that great whites could live to be at least 73. In fact, Gregory Skomal, a fisheries biologist at the Massachusetts Division of Marine Fisheries, and his colleagues found great whites grow even more slowly than scientists had thought: The biologists' research, published in January in the journal Marine and Freshwater Research, suggested males take 26 years to reach sexual maturity, whereas females aren't ready to have babies until they're about 33 years old - much later than once thought. So, a much-bigger-than-average shark, like Deep Blue, is likely an older shark. Great white sharks need decades to reach adult size, and they continue to grow throughout their lifetimes.
