Have you ever seen capybaras（水豚）? They were thought to be a kind of pig in the p 1，but now we know that they are the largest rodents（啮齿动物）on the Earth. Guess what! They are new stars on social media now!
Seeing them in the wild，you might be surprised at f 2 because they look like giant guinea pigs，which are in fact one of their closest relatives. Capybaras' bodies are covered in reddish-brown fur. When swimming around，t 3 to their small eyes，noses and hairless ears which are high on their heads，they're able to see the above-water things around them. That's w 4 they can protect themselves from danger easily. A capybara w 5 around 50 kilograms and it can grow to 1.5 metres in length. Female capybaras are usually a little heavier than the males.
Most of them live in South America and like to stay in comfortable places with lots of water. Pantanal，the world's largest freshwater wetland，is a p 6 place for them to live. Capybaras usually eat grass. But they sometimes eat their own poop（排泄物）because it is helpful for them to get all the things they need.
Capybaras are good swimmers and love to play with water. They usually live in g 7 of 10 to 20（and up to 100 during the dry season）. They also like chatting with each other very much. They e 8 themselves by making different kinds of sounds，including purring（发出呼噜声），barking，whistling，cackling and grunting. Each sound has an important meaning，from warning the group of danger to sending signals of leaving. It's like a capybara l 9.
With good personalities，capybaras have become increasingly popular on social media. They get along with almost all the other animals and share their homes with birds and turtles，just like a big animal family living t 10 peacefully. They are calm and don't really care about what goes on around them. Other animals can do whatever they feel like if they don't hurt the capybaras. But if capybaras are aware of a risk，they may attack others to protect themselves.

你见过水豚吗？在过去，它们曾被认为是一种猪，但现在我们知道它们是地球上最大的啮齿动物。你猜怎么着！它们现在是社交媒体上的新星！
在野外看到它们时，你可能会首先感到惊讶，因为它们看起来像巨型豚鼠，而豚鼠实际上是它们的近亲之一。水豚的身体覆盖着红棕色的皮毛。游泳时，多亏了它们位于头顶高处的小眼睛、鼻子和无毛的耳朵，它们能够看到周围水面以上的事物。这就是它们能够轻松保护自己免受危险的原因。一只水豚重约50千克，体长可以长到1.5米。雌性水豚通常比雄性水豚重一点。
它们中的大多数生活在南美洲，喜欢待在有大量水的舒适地方。潘塔纳尔湿地，世界上最大的淡水湿地，是它们居住的理想之地。水豚通常以草为食。但它们有时会吃自己的排泄物，因为这有助于它们获取所需的所有物质。
水豚是优秀的游泳健将，而且喜欢玩水。它们通常以10到20只为一群生活（旱季时最多可达100只）。它们也非常喜欢互相交流。它们通过发出不同种类的声音来表达自己，包括咕噜声、吠声、口哨声、咯咯声和咕噜声。每种声音都有重要的意义，从向群体发出危险警告到传递离开的信号。这就像一种水豚的语言。
由于性格温顺，水豚在社交媒体上越来越受欢迎。它们几乎能和所有其他动物和睦相处，还和鸟类、乌龟共享它们的栖息地，就像一个大型动物家庭和平地生活在一起。它们很平静，不太在意周围发生的事情。如果其他动物不伤害水豚，它们可以随心所欲地做任何事。但如果水豚察觉到危险，它们可能会攻击其他动物来保护自己。
