Emperor penguins are the world's deepest-diving birds. They can dive to depths of approximately 550 meters (1,800 feet) while searching for food. [47]

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. [4] Most inhabit Fernandina Island and the west coast of Isabela Island. [5] The cool waters of the Humboldt and Cromwell Currents allow it to survive
Emperor penguins have four overlapping layers of feathers, keeping them warm. They also reduce heat loss with countercurrent heat exchange systems throughout their body to cool blood as it reaches extremities like the feet. [19] They are the only Antarctic animal to breed during the winter. [12]
