Rudder glands are specialized anatomical structures found in certain species of fish, particularly in the family of fish known as the Opisthocomidae. These glands secrete a mucous substance that helps reduce friction in the water, aiding in more efficient movement and maneuverability. The mucus may also serve as a protective barrier against pathogens and parasites. In some cases, rudder glands are involved in communication among fish through chemical signals.
