[For Seniors] Fun 3-Choice Animal Quiz! Introducing Questions Full of Surprises and Discoveries

there is / to exist / to have

Owls have ears and can distinguish sounds well even in quiet places. Although it’s hard to see, they have ear openings under their feathers, and their left and right ears are offset, allowing them to accurately determine the direction and distance of sounds. By the way, the “ear tufts” on top of their heads aren’t ears—they’re decorative feathers.

to faint

Raccoon dogs are quite timid animals. If they get startled, they faint. You don’t see them much in the city these days, but in the countryside you might come across one. If you do, try not to startle it and just watch quietly from a distance.

To protect the eyes from sand

Since camels live in the desert, it seems their eyelashes have become long to protect their eyes from sand. It’s the same role for humans too—to keep debris from getting into our eyes. Camels have likely grown strong and evolved to thrive in the desert.

22 hours

Eucalyptus leaves, which koalas eat, contain toxins. It’s said they need to sleep for long periods to digest those toxins in their bodies.

hippopotamus

Hippos don’t have sweat or sebaceous glands, so their sweat is different from the colorless, transparent sweat humans produce. A hippo’s sweat is a bit viscous and starts out clear, but gradually turns red. This red “sweat” is said to protect them from sunburn and bacterial infections.

To hear better and to let heat escape

Long ears are a rabbit’s trademark, aren’t they? I’ve heard that these days they’re often kept as household pets. Their long ears help them hear well and release heat. The ears have many blood vessels, and when wind hits them it cools the blood, helping prevent their body temperature from rising.

turtle

It’s known as the longest-lived turtle in the world, said to have been born in 1750 and to have lived until March 2006. That far exceeds the average human lifespan, doesn’t it? It would be great if, as medicine continues to advance, humans could also live long and healthy lives.
