It is a seabird widely distributed along coastlines, inland waters, and urban areas worldwide, belonging to the gull family. Known for its elegant flying posture, sharp vocalizations, and adaptability to food. The body is usually covered with white or gray feathers, and the tips of the wings may have black markings, while the color of the head and tail may vary with the season. The beak is strong and powerful, suitable for capturing and processing various foods, including fish, crustaceans, insects, and food waste discarded by humans. When foraging, they utilize their keen eyesight and flying ability, and sometimes follow fishing boats to catch discarded bait or captured fish.

It is a general term for all species in the bird class and penguin family. Penguins, known as the "boats of the ocean," are one of the oldest waterfowl and are likely to have settled in Antarctica before putting on ice armor on Earth. There are a total of 18 species of penguins in the world, most of which are distributed and live in the southern hemisphere. Penguins can live and reproduce in extremely cold climates. It looks like a Western gentleman in a tailcoat, swaying and swaying as he walks, falling and crawling in danger, looking disheveled. But in the water, the penguin's short wings become a powerful pair of "paddles" that can swim at speeds of 25-30 kilometers per hour. You can swim 160 kilometers in a day.
