Penguins are aquatic, flightless birds that are highly adapted your in the water. Their distinct tuxedo-like appearance is called countershading, a form of camouflage that will help keep them safe in the water. Penguins do have wing-bones, though they are flipper-like and extremely worthy of swimming. Penguins are found almost exclusively in the southern hemisphere, where they hook their food underwater and raise their young on land.

Favorites: Krill, fish and squid.
In general, penguins closer to the equator eat considerably more fish and penguins closer to Antarctica eat more squid and krill.


The penguin species with the highest population is the Macaroni penguin with 13, 654, 000 pairs. The species with the lowest population is the endangered Galapagos penguin with between 6, 000-15, 000 individuals.

Penguins can be found in each continent in the Southern Hemisphere from the tropical Galapagos Islands (the Galapagos penguin) located near South America to Antarctica (the emperor penguin).

Penguins can certainly spend up to 75% of their lives in the water. They do all of their hunting in the waters. Their prey can be found within 60 feet of the surface, so penguins do not need to swim in deep water. They catch prey in their beaks together with swallow them whole as they swim. Some species only leave the water to get molting and breeding.

Penguins are social birds. Many species feed, swimming and nest in groups. During the breeding season, some species form substantial groups, or “rookeries”, that include thousands of penguins. Each penguin has a distinct get in touch with, allowing individuals to find their mate and their chicks even in large groups.

Mating Season: Varies depending on the species, though most breed during spring as well as summer.
Incubation: Varies from 1 month-66 days depending on the species.
Number of progeny: King and emperor penguins lay one egg. All other species of penguin set two eggs.

Vector Visual

In contrast to JPEGs, GIFs, and BMP images, vector graphics are not really made up of a grid of pixels. Instead, vector graphics are comprised of tracks, which are defined by a start and end point, along with other points, curves, and angles along the way. A path can be a line, a square, a triangle, or a curvy shape. These paths can be used to create simple drawings or complicated diagrams. Paths are even used to define the characters of specific typefaces.

Simply because vector-based pictures are not made up of a specific number of dots, they can be scaled to a larger size and not lose any image quality. If you blow up your raster graphic, it will look blocky, or "pixelated. " When you blow up a vector graphic, the edges of each object within the graphic stay clean and clean. This makes vector graphics ideal for logos, which can be small enough to appear on a company card, but can also be scaled to fill a billboard. Common types of vector graphics include Adobe Illustrator, Macromedia Freehand, and EPS files. Many Flash animations also use vector graphics, since they scale significantly better and typically take up less space than bitmap images.
