E-PILOT 有夠鯊!! 深藍的食光旅人-姥鯊

from 雷比特生物空中講 · host 雷比特老師

介紹海洋中的溫柔巨人姥鯊(Cetorhinus maximus),牠是現存第二大的魚類,詳細解釋牠特殊的生存機制,包括利用巨大的鰓裂進行高效的衝壓濾食,每小時可過濾數千噸海水。指出姥鯊的身體設計高度專業化,例如牠巨大、富含油脂的肝臟佔了體重的四分之一,用來維持浮力並作為長途遷徙的能量儲備。特別值得注意的是,最新的解剖學研究顯示姥鯊具備區域異溫性,使其在深海環境中仍能維持高於水溫的核心體能,是一種活躍的遷徙性巡航者。然而,姥鯊採取典型的K型生命策略,特徵是性成熟晚且繁殖週期漫長,這使得牠們的族群數量難以恢復。最終,由於歷史上為獲取肝油而進行的工業化捕撈,這種生態平衡中的重要一環目前被國際自然保護聯盟列為瀕危物種。 聽完後可以自主進行線上測驗,檢視學習成效喔~(需要登入gemini) 測驗網址  https://gemini.google.com/share/c510a0391bb4 Powered by Firstory Hosting
