Panaqolus maccus is a small freshwater fish from the chainmail catfish family. It lives on the bottom of rivers in South America and feeds on algae and wood.
Panaqolus maccus differs from other chainmail catfish with its bright striped pattern on the body. It is important for nature because it recycles wood in rivers and helps control algae growth.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
