Audio problem: When Ben shoots at the shark, he falls backwards and pulls no trigger, yet bangs are heard.
Continuity mistake: The same shot of the front of the boat is used over and over again, despite the waves or the speed changing in the wide angles the front is always moving fast on a calmed sea.

Continuity mistake: Cat places a GPS on the shark's tail, and the gadget sticks out as if someone had placed it from behind. But she was on the right side, and aimed straight, so there's no way for the GPS to be in that position.
Continuity mistake: On the boat, the crew is filming the shark approaching. When it swims, bait suddenly appears hanging from the air, which changes to a humongous piece of bait half a second later, together with the climate, that swaps to cloudy, and then in a change of angle the bait is gone and it's sunny again.
Continuity mistake: Before the cameraman is about to be attacked by the shark, he says he's filmed a great scene and gives a high five to Cat two times. The second one, she lifts her right arm but immediately the shot cuts to a close-up where she has her arm down, yet the sound of hands touching is heard.
Continuity mistake: The shark is about to attack the cameraman but instead bites a wooden plank on the boat and withdraws back to the ocean, causing no human or material damage. However, in the following close-up, bite marks appear on the wood.
Visible crew/equipment: After the 2 guys and Cataline arrive at Playa del Rey, one of them looks at her with his sunglasses on. The reflection shows no woman, but a metal structure with a brilliant light flashing.
