Gymnophiona is a group of amphibians that lack the typical hind legs found in most other anurans.
極樂蛙是一種沒有典型後肢的兩棲動物，這與大多數其他無尾目動物不同。
These unique creatures belong to the order Gymnophiona, characterized by their sprawling, legless bodies.
這些獨特生物屬於極樂蛙目，以其四散、無腿的身體為特徵。
The main representatives of Gymnophiona include the caecilians, which are elongated, snake-like animals.
極樂蛙的主要代表包括盲蛇，它們是長形的、類似蛇的動物。
Unlike frogs and toads, members of the Gymnophiona have evolved to move primarily through slithering or burrowing.
與青蛙和蟾蜍不同，極樂蛙目成員已經進化出主要通過蠕動或挖掘的方式移動。
They are often referred to as 'legless' amphibians, but technically, they possess vestigial limbs at the ends of their tails.
常常稱之為“無腿”的兩棲動物，但實際上，他們在尾巴末端保留著退化的肢體。
In the wild, gymnophionans can be found in humid forests and underground habitats in tropical regions.
在野外，極樂蛙可以在熱帶地區的潮濕森林和地下棲息地中找到。
Their skin is usually moist and smooth, aiding in their movement through damp environments.
它們的皮膚通常是濕潤且光滑的，有助於在潮濕環境中移動。
Despite their unconventional appearance, Gymnophiona play an important role in their ecosystems as decomposers.
雖然外表不尋常，極樂蛙在它們的生態系統中作為分解者發揮著重要作用。
Scientists are still studying the unique adaptations and behaviors of Gymnophiona to better understand their evolutionary history.
科學家仍在研究極樂蛙的独特適應性和行為，以更好地理解其進化歷史。
Conservation efforts are necessary for the preservation of Gymnophiona, as several species are facing threats from habitat loss and climate change.
保護極樂蛙免受棲息地流失和氣候變化威脅的保護措施是必要的。
