Two clownfish, Marlin and his wife Coral are admiring their new home in the Great Barrier Reef. They are protecting their clutch of eggs that are due to hatch in a few days. Coral sees a barracuda a short distance away. Marlin tells Coral to get back into the anemone but she tries to protect their eggs. The barracuda then attacks them and Marlin attempts to defend his wife but the barracuda knocks him out. When he regains consciousness, he finds that the barracuda has eaten Coral and all but one of their eggs. He names the last remaining egg Nemo, a name that Coral liked.
