In the water, however, penguins are astonishingly agile. Penguins' swimming looks very similar to birds' flight in the air. [44] Within the smooth plumage a layer of air is preserved, ensuring buoyancy. The air layer also helps insulate the birds in cold waters. On land, penguins use their tails and wings to maintain balance for their upright ...
The emperor penguin breeds in the coldest environment of any bird species; air temperatures may reach −40 °C (−40 °F), and wind speeds may reach 144 km/h (89 mph). Water temperature is a frigid −1.8 °C (28.8 °F), which is much lower than the emperor penguin's average body temperature of 39 °C (102 °F).
Emperor penguins are also known to dive to depths of more than 1,640 feet (500 meters) making them the deepest diving birds in the world, where they are able to hold their breath for up to 20 ...

[3] The males are larger than the females, and the weight of both drops while the parents raise their young.
The African penguin joins the list of species said to be threatened by climate change - and overfishing. Researchers from the UK and South Africa say penguin numbers in the Benguela upwelling ...
The African penguin (Spheniscus demersus), also known as Cape penguin or South African penguin, is a species of penguin confined to southern African waters. It is the only penguin found in the Old World. Like all penguins, it is flightless, with a streamlined body and wings stiffened and flattened into flippers for a marine habitat. Adults ...
