"Sharks that live in deep, cold water could be much older - well over 100," Naylor said. A classic work of nature and humanity, by renowned writer Peter Matthiessen (1927-2014), author of the National Book Award-winning The Snow Leopard and the. She’s around 20 feet long and weighs more than 5,500 pounds. The shark, nicknamed 'Deep Blue' by expert Mauricio Hoyos Padilla, could be one of the biggest great whites ever filmed, according to Discovery, the network that airs 'Shark Week.
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. Deep Blue is one of these sharks she is the world’s largest female great white shark. Stunning footage of what may be the world's largest great white shark caught on camera has resurfaced. But scientists have discovered an absolute chonker of a great white shark, which theyve named Deep Blue and believe to be about 20 feet long. Females typically reach 15 to 16 feet in length. 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. Watch a woman swim up to a chonky 20-foot great white shark like its no big deal. "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. "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. 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. 20 feet long, 8 feet wide, and 2.5 tons in weight that’s Deep Blue. “Emphasis must always be on ensuring divers, kayakers, swimmers and supporting vessels do not intentionally disrupt a shark’s natural behaviour, touch or harass it in any way,” he added.Great white sharks need decades to reach adult size, and they continue to grow throughout their lifetimes. “While it’s great to see a ‘positive’ shark-human encounter given global coverage, we must add a note of caution which holds true for interactions with any large, powerful wild animals,” Richardson said. “While males return to Californian waters, female white sharks often appear to remain offshore.”īut he warned against engaging with sharks as closely as the divers did, stressing that the species can be “unpredictable.” In the latest video, Deep Blue is seen with two other females. “While white shark sightings are rare in Hawaii, satellite tagging shows they make annual migrations from the Californian coast to the middle of the Pacific each winter – including Hawaii,” Richardson said. Deep Blue is a 20-foot-long female great white that was first recorded in 2013 by shark researcher Mauricio Hoyos Padilla.
He added: “If Deep Blue does prove to be pregnant, this is even more significant.” John Richardson, conservation officer at UK organization The Shark Trust, told CNN that the spotting of Deep Blue is “incredibly exciting.” Diver Ocean Ramsey swims alongside the shark.
