What fish cleans whales?

The fish that cleans whales are primarily called cleaner wrasses. These small, colorful fish set up "cleaning stations" where larger marine animals, including whales, come to have parasites and dead skin removed. The cleaner wrasses nibble on the whales' bodies, providing a mutually beneficial relationship where the fish obtain food while the whales enjoy hygiene benefits. Other species, like certain shrimp, also participate in this cleaning behavior.
