Who was the hammerhead from nemo?

The hammerhead from "Finding Nemo" is a character named Bruce, who is a great white shark, not a hammerhead shark. He leads a group of sharks who are trying to abstain from eating fish, adopting the motto "Fish are friends, not food." Bruce is notable for his friendly demeanor, but his instincts occasionally surface, creating tension in the story. His character adds humor and depth to the film's themes of friendship and self-control.
