Continuity: After Hooper and Quint come up from the engine room, there are grease stains all over the front and back of Hooper's blue sweatshirt, that disappear, reappear or keep changing throughout the following shots.

Revealing: At the boathouse, when Hooper cuts open the Tiger shark, this shark is very noticeably different, including its recognizable seams, than the one hanging on the dock earlier.

Continuity: While Quint leads the shark into the shallows, Brody asks, "Have you ever had a Great White do this?" and Hooper is beside the foremast holding one of the rungs, directly under the crow's nest. However, in the next shot, he stands at the edge of the bridge deck, beside the rigging.

Continuity: The damage to the bars of the cage and the top canister changes, and is quite different once Quint and Brody hoist it up.

Revealing: As the shark pushes his face into Hooper's cage, in a very nice close-up of the underside of his pectoral fin the large amount of peeled paint is quite visible, as it is in other shots of other areas of his body. Then in another shot at the same angle, just before Hooper escapes the cage, the paint job is perfect. In some other close-ups the shark's outer flesh creases deeply, because of its hollow interior, when pushed up against other surfaces.

Revealing: After Hooper's comment, "He's working his way up to us," Quint rushes to the stern and shoots another line into the shark. In a very tight close-up of the shark's gills it is very apparent that they are just wide carved ridges, with no slits whatsoever, to even attempt to give the illusion that they are real, like in other great shots of Bruce.

Continuity: Aboard Orca, right beside the yellow barrels on deck, there is something large that is wrapped with green tarp and rope going round it. The tarp and the rope change significantly between consecutive shots throughout their hunt.

Continuity: Just after Hooper remarks, "Fast fish," as they chase the shark, there is a close-up of Brody leaning over the starboard side of the boat, beside the boat's wake. However, in the previous and following wideshots Brody is at the port side of the boat, as it speeds after the shark. Neither are flipped shots.

Revealing: When Brody tries to hail the Coast Guard, just as Quint smashes the radio, the reflection in the center window is of the three windows on the opposite side of the cabin. Though the two side windows being reflected are normal, the entire center window being reflected is blacked out, reason being that the camera filming this shot is positioned in front of that window and in order not to see the outline of the camera, the center window directly behind it was covered. In the previous and following shots obviously there is nothing blocking that window. Similarly, this occurs when Quint speaks with the Coast Guard.

Visible crew/equipment: After Quint walks on deck and tosses the life vests to Hooper and Brody, Quint asks, "Hooper, what exactly can you do with these things of yours?" Just as Hooper turns around, the clear moving reflection of a boom mic and pole are visible on the glass of the door to the cabin, just behind him.

Continuity: After Alex's attack, there is a close-up of the $3,000 reward sign pinned to the board, as the woman complains, "We won't have any of our regular customers..." in the next shot as she continues to say, "We don't even know that there's a shark around here..." the reward sign on the board has different handwriting and is positioned differently on the board.

Continuity: When Hooper removes the pump from the locker, in the close-up Quint takes the pump with his empty hands and gives it to Brody with both hands. However, in the wideshot he is holding the machete in his left hand, as he gives Brody the pump.

Continuity: While Brody and Hooper are at Quint's, just as Quint says, "And don't forget the color TV," the six small shark jaws hanging on the far wall, beside the window to Brody's left, are visible. However, when Hooper ties the sheepshank knot, there are only three small shark jaws beside that same window, near the stove.

Visible crew/equipment: Hooper and Brody grab a couple of poles as the Orca pulls alongside the two floating barrels. When Quint says, "Watch those barrels, boys. Watch them," the crew's vessel is clearly reflected in the cabin's side glass window.

Continuity: Just as the first cleat flies off the stern of Orca, the shape of the small metal hood differs and the entire wood rail at the top of the transom in this close-up differs from the rail in all other shots. The long wood rail has another small piece of wood attached at the end, forming an 'L' shape with a 90° angle, whereas in all other shots the rail is one long solitary piece.

Continuity: When Chief Brody asks, "How many guys you gonna put on that boat?" he stands between two adjacent pilings. Hooper then stands beside the same two pilings in the following wide shots. However, in the close-up when Hooper asks about a good restaurant on the island, he is at the center of the shot standing beside only one lone piling. Richard Dreyfus' beard is also fuller in the close-up, than in the wide shots.

Continuity: When Mayor Vaughn, Hendricks and the others join Brody on the ferry, as they reach the other side of the harbor the coroner's front leans on the car, as he faces the Mayor and Brody. However, in the next shot the coroner's back now leans on the car, as he faces the opposite way.

Continuity: At the beach party, when Cassidy and Chrissie make eyes at each other, in the close-up he sits behind certain people including a girl with blond braids and guy in a denim shirt, with long sleeves. However, in the next wide shot, denim shirt guy has his sleeves rolled up and many of their positions are different.

Continuity: The chum markers, with the yellow flags, disappear and reappear on deck, in consecutive shots within the same scene. For instance, in the wideshot when Quint, Brody and Hooper are splashed and Quint shouts, "Untie us! He'll pull out the transom!" they are gone, but are back in the next shot of the deck. They keep changing positions as well.

Continuity: After Hooper pulls the tooth from the hull of the boat, in the shot just as Ben first pops out, the knife Hooper holds has a protective sheath on the blade, yet in the previous and following shots the pointy serrated blade is not covered.
