Deep Blue, a massive great white shark believed to be 20-plus feet long, made waves this week after being sighted multiple times off the coast of Oahu, Hawaii.

Divers say they saw Deep Blue, touted as one of the largest great white sharks ever recorded, feeding on a sperm whale carcass at the surface about 8 miles off the coast. Then, freedivers were treated with a close-up encounter, with their resulting snapshots going viral worldwide.

The shark, who happens to have its own Twitter account, gained fame after being filmed off Mexico's Pacific coast during Discovery’s Shark Week filming.

Underwater photographer and videographer Kimberly Jeffries stated that "it's been the best news ever to positively ID Deep Blue."

She also noted that there were three unique great white sharks in the area and they have since been named and added to the database as Kainani and Haole Girl. A video she captured (below) shows one of the newly identified sharks, Haole Girl, feeding on the whale carcass.

Jeffries, an experienced underwater camera woman who worked on the Emmy award winning documentary Chasing Coral, described the experience as "absolutely breathtaking."

"It was quite humbling to be in the presence of this great shark," she says. "She is an absolutely beautiful and magnificent being that both commands and deserves respect. That being said, swimming with her and documenting her behavior as she fed and dove and fed for hours over the course of the day was both exhilarating and serene. All her movements were efficient but still beautifully fluid. To be totally honest, I've been a bit more afraid of the media [interest in the video] than I was swimming with Deep Blue."

The shark sighting led others to explore the area, hoping to catch a glimpse of Deep Blue. Another video that surfaced from the same location, which showed shark conservationists and underwater photographers swimming with and sometimes touching the great whites, also drew criticism on social media and reignited an age-old question: “Should we be touching marine life?"

For Jeffries though it's all about the excitement of the encounter and the chance to identify two new sharks and help scientists learn more about their migratory patterns and behaviors. The two new sharks identified were estimated to be between 16 and 18 feet in length. Jeffries says "sharks of this size are quite rarely seen, so it is unbelievably great news to know that other females are growing to a good size and reproducing."
