The hammerhead shark in Finding Nemo is named Anchor.
Anchor is one of the three sharks who try to follow a vegetarian lifestyle. He attends the group’s “Fish Are Friends, Not Food” meetings with Bruce, a great white shark, and Chum, a mako shark. The three friends live in a sunken submarine and attempt to resist their natural predatory instincts.
Anchor’s name is a pun on both his hammerhead shape and the nautical setting of the shark hideout. During the story, the group’s self-control collapses after Bruce smells blood, forcing Marlin and Dory to flee. The other shark names are often confused: Bruce is the great white, Chum is the mako, and Anchor is the hammerhead.
