(CNN) Tiffany Johnson and her husband, JJ, are avid cruisers -- self-described "vacation junkies." In June 2017, the two left their home in Charlotte, North Carolina, and embarked on a relaxing cruise in the Caribbean.
On their final day, the Johnsons chartered a snorkel expedition in the Bahamas.
They took off in a small boat with another couple to a spot 10 minutes from Paradise Island.
Thirty minutes into the snorkeling excursion, Johnson bumped into something.

"I remember even just thinking 'Oh, what did I bump into?' And then when I turned, I was face-to-face with the shark."
