Aptenodytes
Definition
Aptenodytes is a genus within the penguin family Spheniscidae containing the two largest living penguin species: the emperor penguin (A. forsteri) and the king penguin (A. patagonicus). The genus name means 'featherless diver' in Greek. Both species share key traits: they are the only penguins that incubate a single egg on their feet beneath a brood pouch rather than building a nest. Molecular evidence suggests the Aptenodytes lineage diverged from other penguins approximately 40 million years ago, making them the earliest-branching living penguin genus.
