Penguins are a family of 17 to 19 species of birds that live primarily in the Southern Hemisphere. They include the tiny blue penguins of Australia and New Zealand, the majestic emperor penguins of Antarctica and king penguins found on many sub- Antarctic islands, the endangered African penguin and the Galápagos penguin—the only penguin to ...

- General features
penguin, (order Sphenisciformes), any of 18–21 species of flightless marine birds that live only in the Southern Hemisphere. The majority of species live not in Antarctica but rather between latitudes 45° and 60° S, where they breed on islands. A few penguins inhabit temperate regions, and one, the Galapagos penguin (Spheniscus mendiculus), lives a...
The stocky, short-legged appearance of penguins has endeared them to people worldwide. They range from about 35 cm (14 inches) in height and approximately 1 kg (about 2 pounds) in weight in the blue, or fairy, penguin (Eudyptula minor) to 115 cm (45 inches) and 25 to 40 kg (55 to 90 pounds) in the emperor penguin (Aptenodytes forsteri). Most are black on the back and white below, often with lines of black across the upper breast or spots of white on the head. 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.
The total populations of some species, such as the emperor, are estimated in the hundreds of thousands, but most species of smaller penguins certainly run into the millions. Immense island breeding colonies, some teeming with hundreds of thousands of nesting pairs, represent a large potential food resource, but the economic importance of penguins is negligible. Nineteenth-century whalers and seal hunters visited some colonies for meat and eggs, and a penguin oil industry once took large numbers of the birds. By the early 20th century, however, this exploitation was no longer profitable, and most colonies were left alone or actively protected. Some species are now increasing in numbers, apparently as a result of the mid-20th century’s decimation of Antarctic whales, which compete with penguins for the krill (minute crustaceans) on which both feed. Penguin populations, however, are highly vulnerable to changes in climate and ocean temperature, including recent global warming. Penguins also are very sensitive to depletion of local fish populations by humans.
Sep 22, 2014 · Penguins are torpedo-shaped, flightless birds that live in the southern regions of the Earth.
Penguins claim their own family, the Spheniscidae family, and are likely most closely related to other birds like the petrel and albatross. There is still debate over the number of distinct species, but it is generally agreed that there are between 17 and 19 species (see rockhopper and little penguin sections for more information).
Most penguins stay with their mate for many years and lay only one or two eggs at a time. Parents take turns keeping their eggs warm, and when they hatch, feeding and protecting the chicks.
Penguins are a group of aquatic flightless birds from the family Spheniscidae (/ sfɪˈnɪsɪdiː, - daɪ /) of the order Sphenisciformes (/ sfɪˈnɪsəfɔːrmiːz /). [4] They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator.

Penguins are flightless birds often associated with cold temperatures and icy habitats. The most iconic species is the emperor penguin, with its striking black and white feathers and bright yellow accents. While many penguins live in Antarctica, other species, such as the Galapagos penguin, live much closer to the equator in very warm ...
