- They pant and spread their flippers to cool down in the tropical heat
- They are endemic to the Galápagos Islands and found nowhere else
- About 95% of the population lives on just two islands — Isabela and Fernandina
- They survive in the tropics thanks to cool upwelling from the Humboldt and Cromwell Currents
- Their small body size lets them wedge into cool lava caves and crevices to escape the heat
- The only penguin species native to Africa
- Also called the Jackass Penguin because of its donkey-like braying call
- Each penguin has a unique pattern of spots on its chest, like fingerprints
- Their population has declined by over 97% since the early 1900s
- Uplisted from Endangered to Critically Endangered in 2024 by BirdLife International
- Breeding pairs have fallen from around 70,000 in 1980 to fewer than 20,000 today
