Dory manages to refer to Nemo as Fabio, Elmo, Bingo, Chico, and Harpo.

During the end credits, Mike Wazowski (the one-eyed character from
Monsters, Inc. (2001)) can be seen swimming across the screen while
wearing scuba-diving equipment.
When the fish are in bags and the bags are in the ocean, the bags should float with their inner water level at just about the same level as the surface of the ocean.
Nigel recognizes Nemo’s name when he hears the other pelicans talking about Marlin’s journey. But he had not been told Nemo’s name when they met; Nemo was just called “the new guy.”
The ‘trench’ encountered by Marlin and Dory is actually an undersea canyon, since it rises above the ocean bottom. Trenches are miles-deep depressions in the sea floor, like the one where they found the diver’s mask.
The sharks hold their meeting on what appears to be a World War II-era American submarine sunk by a mine strike. It makes no sense for an American submarine to have struck a mine in Australian waters, since during WWII the U.S. had three submarine bases in Australia and would have been fully aware of any mine fields near the coast.
Marlin and Dory are advised to swim to the back of the whale’s throat and then are blown out of the whale’s blowhole. This is not physically possible as whales mouths and digestive systems are not connected to their respiratory system and blowhole.
When Dory and Marlin are hanging onto the whale’s tongue, they look down the throat and see the whale’s uvula. No animals have uvulas. Only humans can claim to have them.
Nigel the pelican has nostrils. Pelicans do not have nostrils. They breathe through their mouth.
Mr. Ray is not a Mr. at all, as he lacks claspers (the male reproductive organs found on rays and sharks.)
When Nemo first enters the tank and he has been introduced to everyone, Peach (the starfish) says, “We have got a live one”, the first time her face is pressed against the glass so no one can hear her. But in the next shot when she says “Root canal, and by the looks of those X-rays, it’s not going to be pretty.” her face is pressed against the glass again and everyone seems to hear her.
Bloat (Long Spined Porcupinefish/Diodon holacanthus) and Jacques (Cleaner Shrimp/Lysmata amboinensis) shouldn’t be in the same tank because invertebrates are the Diodon holacanthus’ main food.
Coral should be bigger than Marlin. Female clownfish are always bigger than their mates (often twice as big).
The diving flag seen on the dentist’s boat is the United States’ “Diver Down” flag (red with white stripe). This flag is not used in Australia, and would not be seen on the Great Barrier Reef. The Australian version is blue and white.
Nigel, the Pelican, is a Brown Pelican, scientifically known as Pelecanus occidentalis. The movie is set in Australia, where there are no Brown Pelicans, instead there is the Australian Pelican, scientifically known as Pelecanus conspicillatus. Both birds look quite different.
When Dory is comforting Marlin in the whale, the animators used the exact same sequence earlier in the movie when Dory meets Marlin for the first time.
