Contrary to popular belief, lobsters are not naturally red. This common misconception arises from how they look when they’re cooked. While alive, lobsters display many different colors. Boiling water breaks down the different colors in lobster shells to expose the natural red pigments in their shell. Interestingly, underneath their shells, lobsters have blue blood. While vertebrates, like humans and fish, have red blood due to the iron found in it, the high copper content in the blood of many invertebrates, including lobsters, makes it blue instead.
The ways lobsters observe the world are also quite different from *that of humans. Though they have eyes, lobsters gain much more information about their environment from the three sets of antennae on their heads. The longest pair is used to poke around and feel their surroundings, while the two smaller sets sense chemical changes in the water. To scare away predators, they can vibrate their outer shells to make threatening sounds.

Lobsters are so much more than just a seafood delicacy — they’re unique creatures with a long history. Take a close second look next time you see one of these cool crustaceans.
這裡的that為單數代名詞，等於 the way，意指人類觀測這個世界的方法只有一種。
與普遍觀念相反，龍蝦並非天生呈現紅色。這種普遍的誤解源於牠們被烹煮時的外觀。活的龍蝦呈現許多不同顏色。沸騰的水會分解龍蝦殼中的不同顏色，使其露出蝦殼的自然紅色色素。有趣的是，在殼之下，龍蝦擁有藍色的血液。像是人類和魚類等脊椎動物因血含有鐵而擁有紅色血液，而許多無脊椎動物（包括龍蝦）血液中的高銅含量則是讓其血液呈現藍色。

龍蝦觀測世界的方式也與人類相當不同。儘管龍蝦有眼睛，但牠們是透過頭部的三對觸角來獲取更多關於環境的訊息。最長的那對用於四處戳探以及感知周圍環境，而另外兩對較小的觸角用來感應水中的化學變化。為了嚇跑掠食者，牠們可以震動其外殼來發出具威脅性的聲音。
龍蝦不僅僅是美味的海鮮佳餚，牠們是一種歷史悠久的獨特生物。下次你看到這些酷炫的甲殼動物時，不妨再仔細觀察一下。

It’s likely that you may know someone who has had their appendix removed, or at least you’ve heard of the operation. An appendectomy is typically performed when the appendix, a small pouch next to the intestines, becomes inflamed or infected, leading to severe pain and potential complications if left untreated. Fortunately, the procedure is very safe today, and patients can go on to live normal lives without their appendix. Yet, it still begs the question of how humans can continue living without an organ. The human body is full of various parts that scientists still don’t completely understand, and
Wisdom teeth are another example of vestigial organs. Why do humans have wisdom teeth? One theory suggests that they were originally intended to help support muscles and tissues in the human face. Another theory indicates that they were initially meant to aid our ancestors in chewing certain tough foods that grew in the wild. As our diets have softened with processed foods, these teeth may become less necessary. Removing one’s wisdom teeth can feel like a rite of passage for many young adults. At some point in their late teens to early twenties, most people will have up to
