Deep Blue is a female great white shark that is estimated to be 6.1 m (20 ft) long and is said to be over fifty years old. The shark was first spotted in Mexico by Mauricio Hoyos Padilla, a researcher. Various videos have shown the shark to have been calm and non aggressive around humans and notably even a few dolphins.

Deep Blue was first discovered in 2014 when she was filmed as part of Shark Week off the coast of Guadalupe Island, Mexico

Today (Jan 15th) was extremely special because while I (Ocean Ramsey) work with (great) white sharks all around the world they are extremely rare in Hawaii and this individual may be one of the largest recorded and shows similar markings to “Deep Blue” a shark I’ve studied in Isla Guadalupe, Mexico where I’ve done most of my work with white sharks.

This gentle giant swam up and brushed up against our boat repeatedly. There is a theory that large females come here when they are possibly pregnant trailing whales. There was a dead sperm whale in the area and we did observe her from a distance swimming over to it and eating it on a regular basis throughout the day. Sharks role in the ecosystem, to pick off the dead, dying, weak, wounded, sick, injured, etc. there by keeping lower trophic levels healthy and in balance.

Shark experts believe Deep Blue is still out swimming.

Deep Blue was tagged in 2014. The tag was temporary and couldn’t be tracked long because it was a short lasting transmitter.

On OCEARCH, you can track over 100 other great white sharks.
