Nina has recently spent two days with Oceana in a district of the Bahamas called Bimini to help protect sharks. Nina’s photo of herself underwater next to a shark with nearby plankton and corral along the seabed; looked as though Nina certainly enjoyed her underwater adventure and participating in the Oceana cause. It was alluded to that there would be at least one video by the mention of “Stay tuned for more sharky goodness” from Nina’s social media post.

Before Nina confirmed via an Instagram post referencing a location in Hawaii that there will be at least one video filmed; most probably as part of the #FinBanNow Oceana campaign and that filming is actually continuing,

Oceana is a good cause as their mission statement is as follows,

“Working hard to protect our oceans. Fighting against offshore oil and destructive fishing. Fighting for clean energy, sharks and turtles.”
