The giant blenny is a large marine fish from the blenny family. It lives among rocks in coastal waters of the eastern Pacific Ocean and feeds on algae.
The giant blenny differs from other blennies in its larger body size and strong teeth. It helps maintain the balance of algae on rocky reefs and serves as food for larger fish.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
