The Albino Penguin (Aptenodytes albus) is a fictional species of penguin which appears in H. P. Lovecraft's 1936 novella At the Mountains of Madness. The narrator, William Dyer, describes them as standing six-feet-tall, making them larger than even the Emperor Penguin, which in reality is the tallest and heaviest of all living penguin species.
The modern Albino Penguins discovered by Dyer and Danforth in At the Mountains of Madness are concluded through sculptures to be descendants of archaic penguins bred by the Elder Things. When Antarctica became glaciated, the penguins retreated to a heated underground abyss, although years of evolution in these depths "destroyed their pigmentation and atrophied their eyes to mere useless slits."
