A close encounter with a tiger shark was caught on video off the North Shore of Oahu, Hawaii.
Ocean Ramsey, a marine scientist and free diver, was having what she described as a normal day when she nearly dove into the mouth of a "friend" - Queen Nikki, as a certain tiger shark in the area is called.
Ramsey said she's known this particular shark for nearly 20 years - and was excited to see her again.

"Sharks like Queen Nikki are rare to see, let alone encounter - and I've got thousands of dives and decades of experience," Ramsey told Fox News Digital.
"She is one of my absolute favorite tiger sharks," she also said.
In the video, Ramsey can be seen about to dive into the ocean water when Queen Nikki jumped up at her, splashing her fins.
Ramsey said she had seen this shark just moments earlier, when she jumped in the water to redirect Queen Nikki and grabbed a piece of plastic floating in the water.

"I didn't realize how bad the visibility was in my rush until I saw her white belly coming up out of the haze," she said.
Ramsey believes the shark was moving quickly toward the school of fish that were hiding under their boat.
"The white on the bottom of my fins, the splashing from my fins and the dive ladder and shadow cast probably added to her excitement," she said.

Although this was a close encounter, Ramsey said she and her team continued on with their day - and did dive in the same area immediately after they caught that moment on video.
Ramsey said she simply waited for Queen Nikki to pass.
She then looked for other sharks before getting back in the water.
Ramsey was diving as she does every day for the One Ocean Ramsey organization.
One Ocean Ramsey is an organization that Ramsey and Juan Oliphant founded. He's a professional shark conservation photographer - and their goal is shark conservation.
The organization also offers snorkeling opportunities to the public. They teach people about shark behavior and how to enjoy time with the predators rather than fear them.

Oliphant told Fox News Digital that this particular day of diving was special - but that the show must go on.
"We laughed and got in the water with these misunderstood apex predators to conduct our usual research and collect more footage for our conservation efforts," he said.
The organization also records physical changes in local sharks for their shark identification database.

"We always evaluate shark behavior before inviting others to join us in the water," he said.
The organization recommends that anyone interested in shark diving only do so with a professional.
Ramsey and Oliphant are co-authors of the book, "What You Should Know About Sharks: Shark Language, Social Behavior, Human Interactions and Life-Saving Information."
