In “Finding Nemo,” the forgetful blue tang is Dory.
Dory is a regal blue tang who meets Marlin while he searches the ocean for his son, Nemo. Her short-term memory loss makes it difficult for her to retain new information, so she often forgets where she is going or what she has just been told. Despite that challenge, her optimism, empathy, and determination make her an essential companion on the journey.
Dory’s memory problem is a storytelling trait rather than a precise medical diagnosis. She can still remember skills, emotions, and important fragments of her past, which helps her recognize clues and persist when the search becomes dangerous. Her famous phrase, “Just keep swimming,” captures her strategy for coping with uncertainty.
Dory is a blue tang, while Nemo and Marlin are clownfish. Crush is the laid-back green sea turtle who helps the group travel through the East Australian Current. Dory later becomes the lead character of Finding Dory, which reveals that she was separated from her parents as a child and sets out to find them.
The character was voiced by Ellen DeGeneres in both films, making Dory one of Pixar’s most recognizable characters.
