The Fernandina giant tortoise is one of the rarest species of land tortoises. It lives only on the volcanic island of Fernandina in the Galapagos archipelago and is distinguished by its very large size.
The Fernandina giant tortoise is distinguished by its saddle-shaped shell with sharply raised edges. It is important for the island's nature because it disperses plant seeds and maintains vegetation diversity.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
