Trachycorystes trachycorystes is a freshwater catfish with a body covered in sharp spines and bony plates. The fish lives on the bottom of Amazon basin rivers and leads a nocturnal lifestyle.
Trachycorystes trachycorystes differs from other catfish with very rough armor and sharp spines on its body and fins. It helps keep the river bottom clean by eating leftovers and serves as food for larger fish.
Locomotion through water employed while searching for or capturing prey.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
