E-PILOT 遊認有魚系列~無頷魚戰記-盲鰻與八目鰻

from 雷比特生物空中講 · host 雷比特老師

深入探討脊椎動物演化樹上最早分支的無頜總綱,主要聚焦於盲鰻和八目鰻,強調它們是跨越數次大滅絕的高度特化生存大師,而非演化停滯的「活化石」。基因組學證實兩者共同組成圓口綱單系群,並揭示盲鰻的無脊椎狀態並非原始,而是為了適應深海環境而主動發生的特徵退化。這兩種生物的生存策略截然不同,盲鰻演化出四個心臟與能在0.4秒內膨脹萬倍的超級黏液作為防禦武器,而八目鰻則具備罕見的程式化基因組重排能力以及能從海中溯河的滲透壓調節機制。亦介紹人類修建威蘭運河如何導致海八目鰻入侵五大湖,造成湖鱒漁業崩潰的生態浩劫,並詳述目前主要透過針對幼體的殺鰻劑TFM進行持續的族群控制。 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/9c0c0b115514 Powered by Firstory Hosting
