STANDARD FACTS ABOUT PENGUINS



Penguins are aquatic, flightless birds that are highly adapted to our life in the water. Their distinct tuxedo-like appearance is called countershading, a form of camouflage in order to keep them safe in the water. Penguins do have wing-bones, though they are flipper-like and extremely best for swimming. Penguins are found almost exclusively in the southern hemisphere, where they find their food underwater and raise their young on land.
Diet
Fan faves: Krill, fish and squid.
In general, penguins closer to the equator eat far more fish and penguins closer to Antarctica eat more squid and krill.

Inhabitants

The penguin species with the highest population is the Macaroni penguin with 14, 654, 000 pairs. The species with the lowest population is the endangered Galapagos penguin with between 6, 000-15, 000 individuals.

Range
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).

Behavoir
Penguins could spend up to 75% of their lives in the water. They do all of their hunting in the normal water. Their prey can be found within 60 feet of the surface, so penguins do not have to swim in deep water. They catch prey in their beaks plus swallow them whole as they swim. Some species only leave the water intended for molting and breeding.

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

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

Vector Image

As opposed to JPEGs, GIFs, and BMP images, vector graphics are certainly not made up of a grid of pixels. Instead, vector graphics are comprised of ways, 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 sophisticated diagrams. Paths are even used to define the characters of specific typefaces.

Due to the fact vector-based photos 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 a good raster graphic, it will look blocky, or "pixelated. " When you blow up a vector graphic, the edges of each object within the graphic stay even and clean. This makes vector graphics ideal for logos, which can be small enough to appear on a enterprise 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 more beneficial and typically take up less space than bitmap images.
