Revealing: When the megalodon attacks the yacht the party goers jump off the yacht, and some of them reach the large round safety raft. To the raft's right, there is a visible yellow line attached to it so it doesn't drift away for the shots.

Revealing: When the megalodon appears, Ben shoots a flare into the sky, which catches the attention of Hector who is flying in the chopper. In the exterior shot of Hector's reaction, there is a reflection of a fence on the side of the chopper, even though Ben signaled for help while out in the ocean.

Factual error: The megalodon tooth shown in the film is actually not from a megalodon. It seems to be related to the genus Isurus, the mako shark, or maybe the Cosmopolitodus, which most scientists identify as the ancestor of the great whites. The tooth doesn't have a v-shaped root, it is laterally compressed and lacks a scar and fine serrations.

Continuity: During one scene, in numerous shots Ben pushes the throttle lever all the way up, but in shots between he never actually pulls the lever down.

Continuity: When Ben takes the photograph of the shark tooth to have it analyzed, he hold the tooth as he uses his digital camera. The camera is not connected to his computer, but the picture appears anyway. Also, Ben's fingers are not holding the tooth and the photo doesn't have a background.

Continuity: The lifeguard runs to the shore telling people to get out of the water, and passes by some people on the beach. There's a two-second-long shot of the swimmers, and suddenly the previous scene is repeated for no reason at all. The lifeguard is away from the shore running towards the water again, and all the people on the beach have vanished.

Continuity: The waitress hands Ben the tray with coffees and withdraws her hands from the counter. Immediately afterward, they're on top of it again.

Audio problem: When Ben takes a picture of the camera (when transferring the tooth photo) it makes a totally different sound to that when Cat uses it.

Continuity: After picking up the lobster, Ben is inside a boat, but disappears from it in the wide angle.

Revealing: After Ben picks up the lobster and the shark tooth, he gets in a boat that starts to turn around. The close-up of him shows the background still.

Continuity: After the incident with the seal and the shark, the couple are explaining it all to a cop who writes it down on a notepad. In the close-up it changes to a pink bottle, and in the wider angle back to a notepad.

Continuity: After the mating couple in the sea scene, Ben is watching the dead shark and the couple are in the back with a cop. When the angle changes, the woman is now sitting on the car's hood and a cop has suddenly appeared on the left side.

Factual error: On the Mexican beach, a girl jumps over a fence with a sign that reads "Cierado - Closed". The correct spelling is "Cerrado".

Revealing: While the shark eats the raft with the people in it, the whole raft, including its inside, has been deleted except for its border.

Continuity: Ben is about to shoot the flare while Cat grabs the aid kit. Half a second later, an aerial shot shows the box floating in the middle of the ocean.

Continuity: After Ben brings the first aid kit, the size of the sunken ship is very narrow, but from a wide shot it's much wider.

Continuity: Everyone in the Apex yacht falls down when the shark knocks the ship violently, but the fragile tower made of champagne glasses manages to defy the laws of gravity, and it doesn't move an inch amidst the chaos until a waiter stumbles upon it.

Continuity: After a woman falls off the Apex yacht, a man falls down, and when he is about to hit the water a raft suddenly appears.

Revealing: The shot of the shark opening its mouth to eat the politician from the yacht is the same one used for when Ben and Cat where climbing the rope to get on the helicopter.

Continuity: When the parasailing woman is in the water and grabs Cat's hand, from a front angle the parasail is in front of her. From the back shots, it totally disappears.
