The barracuda is seen in the beginning of the film as it looks at Marlin and Coral. Coral sees her eggs and rushes to protect them. The moment she moves, the barracuda attacks. 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 later changed to a deleted scene because it would have scared little kids watching the movie.
- Despite barracudas and other fish not having vocal cords and as such not being able to produce any sounds, 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, barracuda do not eat clownfish (or any other kind of fish) eggs.
- In the 3-D rerelease, when the barracuda closes its teeth, its bottom lip is shown.
