🛡️ 三國動物園 | Three Kingdoms Zoo 🦈 鯊魚科普 | Shark Facts 第16篇 / Episode 16 鯊魚的睡眠與休息 / Sleep and Rest 🌊 睡覺方式很特別 / Unique Sleep 鯊魚沒有像哺乳類那樣閉眼長時間睡眠，它們通常是半休息狀態。 Sharks do not sleep like mammals; they often enter a resting state without fully shutting down. 必須游動呼吸的鯊魚（如大白鯊） Sharks that must swim to breathe (ram ventilation sharks) 👉 不能完全停止游動 👉 Cannot fully stop moving 👉 只能進入類似“放鬆肌肉、降低活躍度”的狀態 👉 Enter a state of relaxed muscles and reduced activity 能靜止呼吸的鯊魚（如某些底棲鯊魚） Some benthic sharks can rest on海床 or coral without游動 👉 可以暫時停下游動 👉 Can stop swimming temporarily 👉 仍然保持警覺以防掠食者 👉 Remain alert for predators ⏰ 一天的休息 / Daily Rest 鯊魚沒有固定“睡覺時間”， Sharks have no fixed sleep schedule, 會間歇性降低活動，進入短暫休息狀態 they intermittently slow down activity and rest briefly. 👥 群體休息 / Social Rest 一些鯊魚會群體聚集休息， Some species rest in groups, 利用集體監視降低被攻擊風險 using collective awareness to reduce predation risk 彼此之間保持距離，避免碰撞 maintaining space to avoid collisions 💡 冷知識 / Fun Fact 雖然休息，但鯊魚的感覺器官仍然活躍，能即時反應 Even while resting, their sensory organs remain active and responsive
