4 hours ago -The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species and is endemic to Antarctica. The male and female are similar in plumage and size, reaching 100 cm (39 in) in length and weighing from 22 to 45 kg (49 to 99 lb). 1 month ago -Colour is rare, being limited to red or yellow irises of the eye in some species; red beaks or feet in a few; yellow brow tufts in the three species of Eudyptes; and orange and yellow on the head, neck, and breast in the emperor and king (A.
patagonica) penguins. Most birds have hollow, air-filled bones to help them stay light for flight. Penguins adapted with solid bones instead.
Penguins do have feathers—they’re just more densely packed and oily than the feathers of most other birds. This gives their bodies a slick, smooth appearance and helps them stay warm and swim well. All adult penguins are countershaded: dark on the dorsal (back) surface and white on the ventral (underside) surface.
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. A penguintypically has a black back and a white belly.
Different types range in height from about 14–45 inches (36–114 centimeters).
