Nemo is a young clownfish who lives with his father, Marlin in a sea anemone. Before he hatched from his egg, Nemo’s mother, Coral, and the other eggs were killed in an attack by a barracuda.
Only Nemo’s egg survived, albeit slightly cracked. As a result of the egg damage, Nemo’s right fin is smaller than the left, thus Marlin worries about him and becomes overprotective of his only son. He was given his name because Coral mentioned she liked “Nemo” as a name while they were looking at their eggs. He is very eager to go to school at the beginning of the movie, but lazy at the end. He is also quite friendly with anyone he meets.
