"The diver who collects specimens of underwater life has fun and becomes a keen underwater observer. .. seek slow-moving or attached organisms such as corals, starfish, or shelled creatures." (Golden Guide to Scuba Diving, 1968)
The shark is named Deep Blue, it’s the largest living Great white that’s currently known. They found her after feeding on a whale carcass so the shark is basically in a food coma which is how they can swim with her. I forget the free divers name but she is basically a glorified model. The real issue here is they broadcasted Deep blue’s location, her jaws hanging on wall somewhere is a big temptation to a lot of people.
