Almost all animals need to sleep to stay healthy. But sleeping can also be dangerous because other animals may hurt those who are sleeping. This leads to many different ways of sleeping that help them stay safe. Some of these ways may surprise you!
Almost all bats sleep upside down. They hang from a branch of a tree or the ceiling of a cave. Up high, bats are safe from most other animals. If they are in danger, they just fly away.
A dolphin sleeps with just half its brain at a time. It must stay awake to breathe and to watch for danger. Dolphin mothers and babies can go without sleep for as long as two months to stay safe.
Some ducks sleep with just half their brains, too. These ducks often sleep in a line. The ducks at both ends help to keep the group safe. They keep one eye open to watch for danger. The ducks in the middle sleep deeply with both eyes closed.
Seals breathe air, but that doesn't stop some of them from sleeping underwater. They hold their breath and dive deep to sleep for up to twenty minutes at a time. Sleeping deep underwater helps these seals stay safe from animals that hunt them near the surface.
Horses often sleep standing up. Their legs lock in place so they don't fall over. If a horse is lying down, it needs a long time to get up. A horse can run from danger more quickly if it is already standing.
A flamingo can sleep while standing on one leg. The standing leg locks so it stays straight. The other leg remains close to the flamingo's body. Its head rests on its back. A flamingo lives (and sleeps) near many other birds to stay safe.
Some seabirds can sleep while they fly. These large birds spend most of their lives over the ocean. They are in danger on the water, but they are safe in the air. They fly for many hours without flapping(拍打)their wings. Sometimes they sleep while they are flying.
Would you like to sleep how they sleep?

Can you recognize (辨别) AI-made pictures among real ones? Mark Zuckerberg wears a pink coat and walks in the fashion show. Former US president, Donald Trump, falls over while {#blank#}1{#/blank#} is getting arrested (逮捕). These pictures have {#blank#}2{#/blank#} popular online recently. They have one thing in common—they are fake (假的), but they look real.
AI tools, like Midjourney and DALL-E, {#blank#}3{#/blank#} create such pictures. Simply type in what you want and the picture comes out in a few minutes. People have never been {#blank#}4{#/blank#} worried than today about the fake news.
However, AI tools are not perfect. News medias, including the Washington Post and the Paper gave some {#blank#}5{#/blank#} on recognizing fake pictures.
One way is to look at hands. Human hands are often {#blank#}6{#/blank#} incorrectly by AI. The photos AI uses to learn often show hands in different ways, so it isn't sure what a "hand" {#blank#}7{#/blank#} looks like.
The other way is to {#blank#}8{#/blank#} attention to the details. For example, people in an AI made picture may miss an earring or a part of their glasses. If there {#blank#}9{#/blank#} a text in a picture, the text is usually unreadable. AI is also terrible at dealing with the background. If there's a crowd in the image, {#blank#}10{#/blank#} faces in the corner are usually unclear—or they don't have a face at all!
