For camouflage

The reason penguins are black and white is for camouflage that protects them from predators. Seen from below in the ocean, their black backs blend into the darkness of the deep, and their white bellies blend into the brightness of the sky, making them harder for predators to spot. This coloration pattern is called countershading and helps protect them from predation.

toboggan

The act of penguins moving by sliding on their bellies over snow or ice is called “tobogganing.” This behavior helps them conserve energy and increase speed; by using their feet to propel themselves while sliding, penguins can travel efficiently.

birds

Penguins are classified as birds because they have feathers and reproduce by laying eggs. Although they cannot fly, evolution has streamlined their bodies and transformed their wings into flipper-like structures, enhancing their mobility underwater. As a result, penguins are excellent swimmers and may sometimes appear fish-like, but biologically they are firmly members of the bird family.

while standing

Penguins spend a lot of time standing, and in fact, it’s common for them to sleep while standing. Because they can stabilize their bodies and maintain balance even during sleep, they are able to rest in this way.

Because having feathers covering the body keeps the skin from getting wet.

The reason penguins can swim for long periods in cold seas lies in their feathers. Penguin feathers are extremely dense and waterproof, preventing seawater from directly touching their skin. Thanks to these feathers, penguins can maintain their body temperature and swim for extended periods even in frigid seawater.

about 15 to 20 years

The average lifespan of penguins varies by species, but it is generally considered to be around 15 to 20 years. In the wild, lifespan is affected by predators and environmental conditions, but penguins living in human-protected environments can sometimes exceed the average lifespan with proper care and management.

Flipper

A penguin’s wings are called flippers, and they are shaped to provide propulsion while swimming. They enable excellent maneuverability underwater, characterized by movements akin to those of birds flapping their wings, showcased when penguins swim.

Emperor penguin

The emperor penguin is considered the largest of all living penguin species, reaching about 115 centimeters in length and weighing approximately 22 to 45 kilograms. Found mainly around the Antarctic continent, it is known for its impressive appearance adapted to the harsh environment.

once a year

The complete replacement of a penguin’s feathers once a year is called molting. During this period, penguins expend a great deal of energy, so they often come ashore to focus on growing new feathers. With the fresh plumage, their insulation and waterproofing are maintained, enabling them to survive in harsh environments.

Ueno Zoo

The correct answer is Ueno Zoo. In Japan, Ueno Zoo is regarded as the first zoo to successfully keep penguins. Penguins began to be kept there in the early years after the zoo opened, and ever since, it has remained a beloved spot where many people go to see penguins.
