The barracuda is seen at the beginning of the film as it looks at Marlin and Coral. Coral sees her eggs and rushes to protect them. Marlin tries to help Coral, but the barracuda knocks Marlin unconscious and eats Coral and her eggs, except one that later becomes Nemo.
- In the original storyboard of the movie, there was going to be a scene where Coral and the eggs were seen inside the barracuda's mouth, but it was later cut from the final film because it would have scared little kids watching the movie.
- The Barracuda can be heard roaring as it attacks Marlin and Coral. In a similar vein to Glut the Shark from The Little Mermaid, this may have been done merely for dramatic purposes.
- In real life, barracudas do not eat clownfish (or any other kind of fish) eggs. Instead, they eat jacks, grunts, groupers, snappers, small tunas, mullets, killifishes, herrings, and anchovies.
- In the 3-D re-release, when the barracuda closes its teeth, its bottom lip is shown.
- As revealed through the Finding Dory commentary, one of the writers for Finding Dory wanted the last shot of the sequel to be the Barracuda looking hungrily at the reef right before "The End" appears on the screen.
- Although Nemo survived the barracuda's attack, his egg got a slight damage from it, a small crack which is why Nemo's right fin is so small.
- A Barracuda that resembles the Barracuda in Finding Nemo makes a cameo appearance in Toy Story 4 where it was stuffed and mounted on the wall of the antique store.
