SIMPLE FACTS ABOUT PENGUINS



Penguins are aquatic, flightless birds that are highly adapted to our lives 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 fitted to swimming. Penguins are found almost exclusively in the southern hemisphere, where they get their food underwater and raise their young on land.
Diet
Worn: Krill, fish and squid.
In general, penguins closer to the equator eat a lot more fish and penguins closer to Antarctica eat more squid and krill.

Human population

The penguin species with the highest population is the Macaroni penguin with 10, 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 can easily spend up to 75% of their lives in the water. They do all of their hunting in the h2o. 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 along with swallow them whole as they swim. Some species only leave the water regarding molting and breeding.

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

Processing
Mating Season: Varies depending on the species, though most breed during spring in addition to summer.
Incubation: Varies from 1 month-66 days depending on the species.
Number of young: King and emperor penguins lay one egg. All other species of penguin lay down two eggs.

Vector Graphical


Not like JPEGs, GIFs, and BMP images, vector graphics are not necessarily made up of a grid of pixels. Instead, vector graphics are comprised of methods, 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 intricate diagrams. Paths are even used to define the characters of specific typefaces.

Since vector-based graphics 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 some raster graphic, it will look blocky, or "pixelated. " When you blow up a vector graphic, the edges of each object within the graphic stay light and clean. This makes vector graphics ideal for logos, which can be small enough to appear on a organization 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 greater and typically take up less space than bitmap images.
