達(dá)爾文蛙見(jiàn)于南美洲大部分地區(qū)，它們撫育幼蛙的方式與眾不同。達(dá)爾文雌蛙產(chǎn)下卵后，雄蛙用舌頭把卵卷起咽到聲囊里，之后雄性達(dá)爾文蛙則繼續(xù)進(jìn)食。當(dāng)蝌蚪長(zhǎng)到?jīng)]有尾巴時(shí)，雄蛙便張開(kāi)嘴，讓蝌蚪們跳出去。

Frog（達(dá)爾文蛙）: The male Darwin frog hatches his eggs in a pouch（文中指“蛙的聲囊”） in his mouth. He can eat and continue about his business until his tadpoles （蝌蚪）lose their tails, become tiny frogs, and jump out of his mouth!
