- There is no food at the edge,
河边没有一点食物 - but this desert river holds a secret.
但是这条沙漠河流却藏着一个秘密 - Each day blackfly rise from turbulent stretches of the river.
每天 成千上万的蚋从奔腾的河水中羽化 - This is what the lizards have come for.
这就是蜥蜴到此的目的 - The black fly never land,
蚋不会降落 - so the lizards have to leap for their food.
所以蜥蜴必须跳起来捕食 - In one day each of these acrobatic little lizards may catch 50 flies.
每只身怀绝技的小蜥蜴 一天能吃掉50多只小虫
