All adult penguins are countershaded; that is they are dark on their dorsal (back) surfaces and white on their ventral (underside) surfaces. The dark dorsal side blends in with the dark ocean depths when viewed from above. The light ventral side blends in with the lighter surface of the sea when viewed from below. The result is that predators or prey do not see a contrast between the countershaded animal and the environment.
2. Many species have distinct markings and coloration.
a. The emperor has a black head, chin, and throat with broad yellow ear patches on the sides of the head (Marchant, 1990).
b. The king penguin has a black head, chin, and throat with vivid orange, tear-shaped ear patches. The orange coloration extends to the upper chest (Marchant, 1990).
c. The Adélie has a black head. Distinctive white eye rings appear during the breeding season (Marchant, 1990).
d. The gentoo has a black head with white eyelids, and a distinct triangular white patch above each eye, usually extending over the head (Marchant, 1990).
e. The top of a chinstrap's head is black and the face is white, with a stripe of black extending under the chin.
f. The crested penguins (genus Eudyptes), such as the rockhopper and macaroni, are distinguished by orange or yellow feather crests on the sides of the head, above the eyes.
g. The yellow-eyed penguin, as its name suggests, has yellow eyes and a stripe of pale yellow feathers extending over its dark head.
h. The fairy penguin, also known as the little blue, has slate-blue to black feathers and a white chin and chest.
i. Temperate penguins (genus Spheniscus), such as the Humboldt and Magellanic, have unfeathered fleshy areas on the face and one or two distinct black stripes across the chest.
