At 8:31 Dr. Yost says "Great whites don't just kill people on boats. What's next, they fly through tornadoes?". This is an obvious reference to the Sharknado (2013) films, which are also produced by the The Asylum studio.
This movie is a follow up on "3-Headed Shark Attack" (2016).
Filmed on location in Puerto Rico, thanks to the Commonwealth of Puerto Rico, the Puerto Rico Film Commission and its Film Incentives Program.
