科學圖說 Introduction
等待雨天,為什麼呢?這是一種兩生類特別的產卵方式,媽媽並沒有把牠們產在水裡,而是產在泥土地上,靠著夏日午後的雷陣雨,將牠帶到水域裡。太早容易缺氧淹死,太晚則容易乾死,只有當蝌蚪外鰓已經長出,可以在水中呼吸時才是最佳時刻。這時候的牠們殷殷期盼雨天的來臨,豐沛的雨水融化牠們的卵膜,將牠們沖到水域內,在水中渡過另一個階段的蝌蚪生活期。
Why does this amphibian wait for the rain? The answer is its unique egg-laying behavior. Females of this frog species lay eggs on mud, relying on afternoon thunderstorms in summer to carry them to the water. If this happens too early, they can die due to hypoxia. If this happens too late, they can die due to dehydration. Once the external gills of the tadpoles have developed, enabling them to breathe in water, they anticipate the arrival of rain and the next stage of their lives.
