The spectacle of blue tears in Fujian led to an outbreak. Do you know how blue tears come from?

In our life, blue tears are actually a kind of sandy microorganisms living on the seabed. The life of this creature depends entirely on the energy of seawater. Leave the sea when the waves wash ashore? Blue tears? Can only survive less than 100 second. When the energy fades, the light of blue tears will fade, and his life will be over. This is a very short life.

In our daily life, the scientific name of Blue Tears is firefly, an ostracod, which is called firefly for short. It is a fluorescent zooplankton that lives in the bay. Marine fireflies have a strange structure called luminous glands. When stimulated by the impact of waves, they will emit light blue light, usually in June and July, they will be distributed in strips along the beach.

? Blue tears? Appearance time: Generally, June-August is the best viewing period every year: it is best to choose a clear night, when dinoflagellate floats on the sea surface, and tides and high tides cause a lot of accumulation, and the south wind blows on the sea surface, making these microorganisms emit blue light and see the scenery clearly! Do you watch the high tide at night? Blue tears? The best time.

So why is it blue and not other colors?

This is because different colors of light travel through the ocean at different speeds. After entering the sea, with the increase of seawater depth, red, orange and yellow light waves are gradually absorbed. At this time, blue light spreads fastest in the ocean. Simply speaking, this is actually a way for shrimp to find a partner. When the male shrimp floats on the sea, in order to attract the female shrimp, it will blink blue light in turn.
