马来西亚红树林萤火虫同步闪烁的自然奇迹
In Malaysia, there is a river called the Selangor River. Along its banks, a mangrove forest grows tall and dark. Every evening, something magical happens here.
Tiny insects called fireflies live in these trees. They have a special power: they can make light inside their bodies. This light is not hot, like your lamp. It is a gentle, cool yellow-green glow.
