Colombia's Caño Cristales（3）

The reason behind the river's color change is the "native" Macarenia clavigera, which accelerates its growth and reproduction with the help of high summer temperatures. It blooms like a rainbow across the uneven riverbed and varying whirlpools. 🌟 Macarenia clavigera exhibits some fascinating characteristics: When the water temperature changes, it shifts between light and dark pink; variations in water level and flow speed cause it to alternate between blood red and purple; differences in sunlight exposure make it oscillate between green and yellow; and under certain conditions, it can even display shades of blue or orange. In reality, its colors are not limited to just five, which is why it is named the "Rainbow River." 🌈 This natural wonder is truly a sight to behold, and its unique beauty is a testament to the incredible diversity of life on our planet. 🌍✨ #Colombia #South America
