Where the name comes from

Aptenodytes means “wingless diver” (a-, without + pterón, wing + dýtes, diver); forsteri honours the naturalist Johann Reinhold Forster, who sailed with Cook. Penguin is of uncertain origin: perhaps from the Welsh pen gwyn, “white head”, a name first given to an Arctic bird now extinct, the great auk.

What sets it apart

The male incubates the single egg on a flap of skin above his feet, standing, for some 65 days of polar night, at −40 °C and in winds of 150 km/h, without eating. He loses almost half his body weight. The thousands of males rotate slowly in a spiral: whoever is at the centre, where it approaches 35 °C, drifts outwards to let in whoever is at the edge. It is an algorithm of fairness, executed by a body that is starving.
