Continuity: When Quint shouts for Hooper and Brody to get their gloves on, in the wideshot Hooper starts to slip his left hand into his left glove. However, in the close-up, he just starts to put his right hand into the right glove.

Continuity: On the Orca near the end of the film, there is a shot of Quint aiming the harpoon gun. In this shot the harpoon gun is high, but in next shot he is shooting from the hip.

Continuity: When Quint gets bitten by the shark, he spits out blood. The blood on his face and chin noticeably changes in consecutive shots.

Continuity: When the shark slams into the cage and makes Hooper drop his weapon, it shows the underside of the shark; look at the its mouth. When the shark is about to slam into the cage again its mouth isn't the same size as it was before. You can tell that they used a real shark when they showed the underside.

Continuity: In the scene where Chief Brody is staring at the water in his chair on the beach, before Alex is attacked, his watch is on his right hand, then suddenly the watch is gone.

Continuity: When the shark is harpooned to some rope, Brody & Hooper tie the rope to the stern cleats, causing the boat to be dragged backwards. Quint gets a machete to cut the rope to limit the boat's damage. At this point the sea is somewhat choppy. He throws the machete making it stick into the edge of the boat. The sea in the background is now completely calm.

Visible crew/equipment: While Quint tells of his experience with the U.S.S. Indianapolis, in the close-ups of Brody a crew member's arm with a watch is clearly visible moving in the reflection on the window, just behind Brody, particularly when Quint says, "Anyway, we delivered the bomb."

Continuity: Just before the Kintner boy is attacked, when Chief Brody is sitting on the beach watching the water, he speaks with the old man called Harry. In the close-up shot of Harry the chin strap of his rubber cap hangs down loose at his chest, but in the side shots the chin strap is tucked up at his ear (seen when Harry stands up).

Visible crew/equipment: When Hooper has found Ben Gardener's head, he screams and drops the tooth and the light. Watch at the bottom of Ben's boat, a wire can be seen to anchor it down.

Visible crew/equipment: When the Orca is sinking and the shark smashes through the glass to get Brody look at it's eyes. You can tell they are fake.

Continuity: When Hooper is gutting the Tiger shark, the order of things he pulls out does not match the order that they land at Brody's feet, as Hooper throws them towards him, and some things just appear at Brody's feet.

Continuity: In a deleted scene, Quint walks into a music store to buy piano wire for his fishing reel. The woman behind the counter is giving a young customer a new clarinet reed and says, "It's a number three. It should be softer than the number two you had." Clarinet reed hardness is categorized with one being the softest and five being the hardest, so a three would be harder than a two.

Continuity: When Quint falls down to the shark there is a shot that shows some legs, (they look like Brody's) slide down behind him. However, Brody is still up in the cabin in the next shot.

Other: During one of the shark scares at the beach, Chief Brody is running along the shoreline telling everyone to get out of the water. There are several frames where the Chief and a man with a moustache are at the water's edge. If you look closely you will notice that the man is laughing and other people laugh as well.

Continuity: In Quint's final scene, just as the shark is thrashing him from side to side, the bandana headband slips off Quint's head. In the very next shot, when Quint is choking on his own blood, the headband is back on his head.

Visible crew/equipment: In the absolutely brilliant boat scene towards the end of the film, there is a medium shot of the rear of the boat when Jaws comes right out of the water. If you look carefully under the shark model as it leaves the water, you can see the mechanical wheel they used to maneuver the model.
