The hornedhead chub is a small freshwater fish from the carp family. It lives in rivers and streams of North America. During breeding, males develop hard bumps on their heads.
The hornedhead crest differs from related species in that males build nests from stones. It is important for river nature because it eats insect larvae and serves as food for predatory 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
