Open guideFrequently asked questions
Which penguins belong to the genus Aptenodytes?
Emperor Penguin, King Penguin all sit inside the Aptenodytes genus, which means they share part of the same evolutionary frame even when their lifestyles diverge.
What is the largest Aptenodytes penguin?
Emperor Penguin is the largest Aptenodytes penguin here, reaching up to 130 cm tall.
Why compare penguins by genus?
Genus lets you compare inherited design before outside pressures start rearranging the story. It is the cleanest way to see which traits belong to lineage and which belong to environment.
