The blue shark is noted for its attractive deep-blue colouring contrasting with a pure-white belly. The whale shark (Rhincodon typus) is a slow-moving, filter-feeding carpet shark and the largest known extant fish species.The largest confirmed individual had a length of 18.8 m (61.7 ft). “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.

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.” This material may not be published, broadcast, rewritten or redistributed.Īrticle originally appeared on LiveScience.Diver Ocean Ramsey swims alongside the shark.

"Sharks that live in deep, cold water could be much older - well over 100," Naylor said. Deep Blue was featured on the Discovery Channels Shark Week.The shark was spotted by marine biologists studying tiger sharks near the island of Oahu, Hawaii. The shark was first spotted in Mexico by researcher Mauricio Hoyos Padilla. 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 a female great white shark that is estimated to be 6.1 m (20 ft) long and over fifty years old. 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. "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. The blue shark is an oceanic and epipelagic shark found worldwide in deep temperate and tropical waters from the surface to about 350 m (1,150 ft). 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-Diving, Educational Snorkel Tours, Whale-Watching & private tours. ![]() That study also showed that great whites could live to be at least 73. 354 Posts - See Instagram photos and videos from Deep Blue Eco-Tours Oahu. 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.
