🛡️ 三國動物園 | Three Kingdoms Zoo 🦈 鯊魚科普 | Shark Facts 第15篇 / Episode 15 鯊魚的一天 / A Day in the Life of Sharks 🌊 日常活動 / Daily Activities 鯊魚大部分時間都在游泳，因為大多數種類需要不斷流動才能呼吸 Most sharks spend most of their time swimming, as many species need constant movement to breathe. 某些鯊魚種類可以停留在海底，但仍需緩慢擺動鰭維持水流 Some species can rest on the sea floor but still need slight fin movements to maintain water flow. --- 🦷 捕食習慣 / Feeding 捕食時間沒有固定模式，視環境與獵物而定 Feeding schedules vary depending on environment and prey availability. 鯊魚嗅覺敏銳，可以從幾百米外偵測血液 Sharks have an acute sense of smell, detecting blood from hundreds of meters away. 捕食方式多樣，有伏擊型、有追逐型，也有群體合作型 Hunting styles vary: ambush, pursuit, or cooperative hunting in groups. --- 💤 休息與睡眠 / Rest & Sleep 大部分鯊魚沒有像人類的深度睡眠 Most sharks do not experience deep sleep like humans. 它們採用半休息模式：部分腦部休息、仍然保持游動 They use “unihemispheric sleep”: part of the brain rests while they continue swimming. 一些種類會靠海流休息，減少能量消耗 Some species rest along currents to conserve energy. 有胎生或卵胎生的幼鯊，會跟隨母體，部分時間休息 Pups of viviparous or ovoviviparous species may rest while following the mother. --- 🤝 社交行為 / Social Interaction 鯊魚大多是獨行俠，但捕食或交配季會短暫聚集 Most sharks are solitary, but gather briefly during hunting or mating seasons. 牠們透過嗅覺、電感應與游動姿勢互相感知 They communicate via smell, electroreception, and swimming gestures. 即便休息，也會保持警覺，隨時應對威脅 Even while resting, sharks remain alert to threats. --- 💡 冷知識 / Fun Facts 鯊魚一生可能會換掉上千顆牙齒 Sharks may replace thousands of teeth in a lifetime. 有些種類白天活動，夜晚休息；有些則夜行 Some species are diurnal, some nocturnal. 游泳不止是捕食，也是保持身體健康與平衡 Swimming serves for feeding, health, and balance.
