青蛙屬於兩棲類動物，壽命一般由一年至十多年不等，是另一類在生命週期中變態的動物。與蝴蝶不同，蛙類只有卵、蝌蚪和成蛙三個階段，牠們沒有靜態的蛹期，變態時依然活躍。由於各生命階段在不同的生境進行，所以要在適當的季節到適當的生境進行觀察。斑腿泛樹蛙在全港廣泛分布，也是龍虎山環境教育中心生機池的常客，讓我們先認識斑腿泛樹蛙，再藉着牠認識蛙類的生命週期。歡迎瀏覽龍虎山環境教育中心網頁:http://www.kadinst.hku.hk/lfseec/zh/elearning.htmlFrogs belong to the family of Amphibians, usually with a life span varies from a year to nearly twenty years. They are also an example that has metamorphosis in the life cycle. However, they differ from butterflies as they only have three life stages without an inactive pupa stage. Frogs remain active during metamorphosis. Since different life stages occur at different habitats, we have to visit the right place at the right time of the year in order to observe their development. Brown Tree Frogs (Polypedates megacephalus) are widely distributed in Hong Kong and they are also one of the regular visitors of the Eco-pond in Lung Fu Shan Environmental Education Centre. This time, let's learn about the Brown Tree Frogs and let them show us the life cycles of frogs.Please visit the website of Lung Fu Shan Environmental Education Centre: http://www.kadinst.hku.hk/lfseec/elearning.html
