Some animals have been known to use tools such as sticks, rocks and even bait to hunt for food. And humpback whales have been found using their own unique tool to hunt — bubbles.

A study published in Royal Society Open Science in August observed the hunting behaviors of more than 70 humpback whales in Stephens Passage in southeast Alaska, documenting how the whales blow bubbles to catch more prey.

Humpback whales hunt for krill — small, shrimp-like creatures that are around the same size as a paperclip, and which swim in swarms.

Whales can take in large amounts of krill in one mouthful. And to make this easier, humpback whales trap swarms of krill in "bubble nets" before feeding on them.

The whales create these "nets" by releasing air from their blowhole as they swim in circles below the surface of the water. The bubbles rise in a spiral pattern, which, from above the water's surface, looks more like artwork than a tool for hunting.

The rising bubbles create "curtains" of air around the krill that they are reluctant to swim through, although researchers aren't yet sure why this is. The whales then swim up through the "net" with an open mouth to eat the trapped krill.

The study data showed that as a whale swam in tighter circles and the "net" got smaller, the krill caught inside became, on average, more than seven times denser. This allowed the whales to catch more krill in a single mouthful.

A whale doesn't have to move very fast to create a net or eat trapped krill, allowing it to get more food without using any more energy.

While not many other animals create their own tools to catch prey like the humpback whale, there are examples of animals using other tools to hunt.

For example, chimpanzees have been observed using sticks to dig for bugs, while sea otters use rocks to open mussels. Certain species of heron have even been found to use food as bait to attract fish.

Câu chuyện về túi khoai tây
Vào một buổi học, thầy giáo tôi mang vào lớp rất nhiều túi nhựa và một bao khoai tây thật to. Thầy  chậm rãi giải thích với mọi người rằng mỗi khi cảm thấy oán giận hoặc không muốn tha thứ lỗi lầm cho ai, hãy viết tên những người mình không ưa hay ghét hận rồi cho vào túi. Chỉ một lúc sau, chiếc túi nào của chúng tôi cũng đã căng nặng, đầy khoai tây. Thậm chí, có người một túi không chứa hết khoai tây, phải thêm một túi nhỏ kèm theo.............

提起博物馆，您大脑里会出现什么样的景象? When you think of museums, what kind of images come to your mind?
恐龙化石、还是出土文物？Dinosaur fossils, or unearthed artifacts?
博物馆的画面基本上都是灰色的，安静地令人肃穆。The museum's images are mostly gray and quietly solemn.
