Their lifespan varies by species, averaging 20 to 30 years, with some living over 70 years. --- 換牙的秘密 / Teeth Replacement 鯊魚一生中會不停換牙。 平均每顆牙齒會使用幾天到幾週不等，然後掉落，由新的牙齒替代。 一輩子可能換掉上萬顆牙齒！ Sharks continuously replace their teeth throughout life. Each tooth lasts from a few days to a few weeks, then is replaced by a new one. Over a lifetime, a shark may replace tens of thousands of teeth! --- 睡眠與休息 / Sleep and Rest 鯊魚沒有像人類一樣的睡眠模式，牠們需不停游動以呼吸。 某些種類可以局部休息，也就是讓一部分腦部休息，而另一部分保持警覺。 有些鯊魚則會在水流中緩慢滑行，以減少體力消耗。 Sharks do not sleep like humans; they need to keep swimming to breathe. Some species can rest one part of their brain while keeping the other alert. Others glide slowly in currents to conserve energy. --- 繁殖方式 / Reproduction 鯊魚的繁殖方式多樣，包括胎生、卵胎生與卵生。 孕期依種類而異，從 6 個月到 2 年不等。 每次繁殖的數量也差別大，有的只有幾隻小鯊魚，有的可以生下上十隻。 Sharks have diverse reproductive methods: viviparous, ovoviviparous, and oviparous. Gestation varies by species, from 6 months to 2 years. Litter size also varies, from a few pups to over ten per reproductive cycle. --- 捕食技巧 / Hunting Skills 鯊魚是頂級掠食者，具有極高的嗅覺和感知電場的能力。 牠們能感應獵物微弱的電信號，準確判斷距離與方向。 這也是為什麼牠們在海洋中幾乎無敵的原因。 Sharks are apex predators, with keen sense of smell and electroreception. They can detect the faint electric signals of prey, accurately gauging distance and direction. This is why they are almost unbeatable in the ocean. --- 社交行為 / Social Behavior 大多數鯊魚是獨行俠，但有些種類會形成小群體。 在休息或覓食時，牠們會保持一定距離以避免衝突。 雖然看似孤單，鯊魚之間仍能透過氣味和行為進行交流。 Most sharks are solitary, but some form small groups. During rest or feeding, they maintain distance to avoid conflict. Although seemingly solitary, sharks communicate through scent and behavior. --- 鯊魚冷知識總結 / Summary of Shark Facts 👉 鯊魚一生會換掉上萬顆牙齒 👉 一部分腦部休息、一部分保持警覺 👉 孕期可長達兩年，繁殖方式多樣 👉 頂級掠食者，嗅覺與電感能力超強 👉 大多獨行，但可群體行動並交流 👉 Sharks may replace tens of thousands of teeth in a lifetime 👉 Part of their brain rests while the other stays alert 👉 Gestation can last up to 2 years, with diverse reproductive methods 👉 Apex predators with exceptional smell and electroreception 👉 Mostly solitary but can act in groups and communicate
