Two clownfish, Marlin and his wife Coral are admiring their new home in the Great Barrier Reef and their clutch of eggs that are due to hatch in a few days. Suddenly, a barracuda attacks them, and Marlin tries to defend and save his eggs, leaving Marlin unconscious. Coral and all but one of their eggs are also eaten. Marlin names this egg Nemo, a name that Coral liked.
