In “Finding Nemo,” Bruce’s eyes turn black when he smells Dory’s blood.
The moment happens after Marlin accidentally strikes Dory with the diver’s mask while the fish argue over the address leading to Nemo. A small amount of blood drifts through the water, and Bruce’s shark instincts suddenly overwhelm his promise to stop eating fish.
Bruce is a great white shark and the leader of a support group for sharks trying to become “ చేప-friendly.” His friends Anchor and Chum restrain him as he chases Marlin and Dory through the submarine, eventually triggering a field of old naval mines.
A common mix-up is remembering that Bruce’s eyes merely widen or that his pupils dilate. The film depicts the change as his eyes becoming completely black, visually signaling his relapse into predatory behavior. Bruce later returns as a supporting character in “Finding Dory.”
