E-PILOT 有夠鯊!! 深海狗鯊?-角鯊目家族

from 雷比特生物空中講 · host 雷比特老師

詳細介紹這群棲息於深海的鯊魚,它們因類似野狗的成群結隊捕食習性而被俗稱為「狗鯊」。解碼該目的科學命名,指出「Squalus」源於其粗糙有鱗的皮膚,而如達摩鯊(Cookiecutter Shark)的屬名則與其腹部的生物發光能力相關聯。該目成員的分類學特徵明確,包括最顯著的判斷標誌——演化上臀鰭的完全消失。它們通常在兩背鰭前緣具備防禦性的硬棘,且缺乏瞬膜,保護眼睛的方式是將眼球向內翻轉。特別介紹明星物種,例如目前已知壽命最長的脊椎動物——可活逾四百歲的格陵蘭鯊,以及利用巧妙的偽裝光環進行圓形咬痕寄生捕食的達摩鯊,展現軟骨魚類深海適應的複雜演化智慧。 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/1648d191521e Powered by Firstory Hosting
