Surprisingly unknown? Trivia Quiz [Multiple Choice: 3 Options]

red

When light enters the ocean, it gets progressively absorbed. Some colors are absorbed more easily than others, and red is the first to be absorbed to the point where it can no longer be perceived. Conversely, blue is less easily absorbed, so it remains recognizable even in the deep sea.

skin

Frogs don’t drink by putting their mouths to puddles; instead, they absorb water through their skin. A frog’s skin is very thin, allowing it to take up moisture directly through the body surface. The belly area in particular is called the “drinking patch,” a structure specialized for water absorption. This skin-based water uptake is crucial for frogs to survive on land, and if conditions become too dry, replenishing water through the skin becomes difficult and can be dangerous.

Once a week

Sloths are very energy-efficient animals, and it’s said that not only their movements but also their bodily functions are slow. For that reason, going to the toilet about once a week is normal. This is thought to be an adaptation to conserve limited energy and to reduce the risks of coming down to the ground. Because descending to the ground to defecate is dangerous for sloths, they have a unique lifestyle of excreting infrequently and all at once.

22 months

The human gestation period is about 10 months, but elephants have an exceptionally long gestation period of roughly 22 months. Among mammals, it is said to be the longest. In addition, there are surprisingly many creatures with long gestation periods: blue whales are about one year, giraffes about 15 months, and orcas about 17 to 18 months.

pebble

Among penguins, there are species in which males court favored females by presenting them with beautiful pebbles. Rockhopper penguins and Adélie penguins are particularly well known for this. Since pebbles are also used for nest building, they serve as important, attractive nesting materials. Isn’t this behavior a sign of the penguins’ ingenuity and close social bonds?

cosmic dust

A shooting star is actually a phenomenon in which tiny specks of dust drifting through space plunge into Earth’s atmosphere, become extremely hot due to friction with the air, and burn up while emitting light. Even particles that are usually very small can flare brightly the moment they enter the atmosphere, and we see them as shooting stars. Many of these dust particles are shed into space by comets and asteroids, and Earth receives several tons of cosmic dust every day.

about 270 degrees

An owl’s neck can rotate up to about 270 degrees. Unlike humans and many other animals, owls have as many as 14 neck vertebrae and a specialized blood vessel structure. Thanks to this, they can survey a wide area without moving their bodies, which helps when targeting prey. Some people may have been startled to see an owl suddenly turn its head toward them while its body was facing the opposite direction.
