It has an area of 642 km (248 sq mi) and a height of 1,476 m (4,843 ft), with a summit caldera about 6.5 km (4.0 mi) wide. It is younger than Isabela, being only less than one million years old since its formation. Like the other islands, it was formed by the Galápagos hotspot. The island is an active shield volcano that has most recently erupted in March 2024.

👉 Fernandina Island in the context of Galápagos penguin
The Galápagos penguin (Spheniscus mendiculus) is a penguin endemic to the Galápagos Islands of Ecuador. It is the only penguin found north of the equator. Most inhabit Fernandina Island and the west coast of Isabela Island. The cool waters of the Humboldt and Cromwell Currents allow it to survive despite the tropical latitude. The Galápagos penguin is one of the banded penguins, the other species of which live mostly on the coasts of Africa and mainland South America. Due to their warm environment, Galápagos penguins have developed techniques to stay cool. The feathers on their back, flippers, and head are black, and they have a white belly and a stripe looping from their eyes down to their neck and chin. Each penguin keeps only one mate, and breeds year-round. Because there are no soft areas to nest, their nests are typically in caves and crevices which also provide protection against predators and the harsh environment. The Galápagos penguin has a lifespan of 20 years, but due to predation, life expectancy in the wild could be significantly reduced. They have been critically impacted to the point of endangerment by climate change and pollution caused by plastic waste due to tourism and urbanization.
