Does a duck have a symbiotic relationship with any animal?

Ducks do not typically have symbiotic relationships with other animals. SymbiOSis refers to a close and long-term interaction between two different species, where both organisms benefit from the relationship. Ducks do have mutualistic relationships with certain species of fish, where the fish eat parasites off the duck's body, providing a cleaning service. However, this interaction is not considered a true symbiotic relationship.
