Have you ever seen "blue tears"? Sparkling and blue, it looks like the sky "sheds" blue "tears" from a distance.
What exactly is "Blue Tears"? In fact, the "blue tears" are luminous algae and sea fireflies. Sea fireflies are tooth-shaped sea fireflies, represented by luminous algae, and sea fireflies have fluorescein and luciferase in their bodies, which react when stimulated by waves, etc., and produce light blue light.
At the turn of spring and summer every year, the temperature rises, the sun shines, the nutrient source in the sea increases, and the vortex flagella that feeds on diatoms is multiplied; this algae is in large groups, and whenever night falls, with the lapping of the waves, blue fluorescent spots constantly appear on the sea surface, especially in the places where the waves on the shore are easy to see, forming the so-called "blue tears".
