Subsequently. The "fluorescent sea" that bursts the circle of friends
Quickly rushed to the hot search on Weibo.
Netizens have said.
It's really romantic.
I also want netizens to say.
I want to go squatting. 
But. Attention friends who want to see the fluorescent sea!
Reduce the influence of external light sources on viewing "blue tears", do not turn on the light, do not turn on the flashlight, do not turn on the flash when taking pictures;
Although "blue tears" need to be stirred by the sea to appear, don't keep throwing stones into the sea in order to provoke "blue tears";
Don't litter and take care of the marine environment;
Note that the beach opening time is 5:30-23:00 on the beach, 8:00-23:00 on the 2nd beach, and 8:00-24:00 on the 4th beach).
In fact. This is not the first time that a fluorescent sea has appeared in the Sai Chung Sea.
In March last year. Near the sea area of Xiyong, Dapeng New Area.
Fluorescent seas have been present.
Why is it coming back so early this year?
The staff of Shenzhen Astronomical Observatory said that this is a temporary natural phenomenon, mainly affected by the recent weather and climate, "when the temperature continues to rise for a period of time, and suddenly the temperature rises, the warm and humid air in the south comes up, and the advection fog on the sea surface, the humidity and high temperature are conducive to the mass reproduction of noctilucent algae and sea fireflies, and the fluorescent sea will come out, plus the light environment of Xichong is good, and you can see clearly (fluorescent sea)".

Blue tears. Just hearing the name is romantic.
What are "blue tears"?
Blue Tears "Can you touch it?"
What are "blue tears"?
It is known that the cause of the "blue tears" is the proliferation of plankton in the ocean, such as noctilucent algae and sea fireflies. Among them, the scientific name of the sea firefly is "Greek-style curvy-throated sea firefly", which is a mesomorphic insect and is a fluorescent animal, and there is a structure called the luminescent gland in its body, which produces light blue light when stimulated by the waves and other stimuli, forming a fluorescent sea.
According to the official Weibo of the South China Sea Bureau of the Ministry of Natural Resources, noctilucent algae have luciferase and luciferin in their bodies, and under the catalysis of luciferase, fluorescein will react with oxygen to produce light, and when stimulated by waves and other stimuli, it will also emit light blue light.
It is worth noting that noctilucent algae are cold-water algae that bloom at their peak in late spring and early summer. When the water temperature exceeds the upper limit of noctilucent algae, the "blue tears" will disappear naturally. "Blue tears" will appear as early as January, erupt in late March and early May, and largely disappear in early June. Depending on the marine environment, the duration of "blue tears" varies from 1 2 weeks to 1 2 months. After sunset, where there is no other light source, "Blue Tears" takes the stage.

See such a romantic scene.
If you have a friend who likes it, you will want to touch it directly with your hand.
I even want to take it home.
May I? Can you take blue tears home?
The algal cells that form blue tears will absorb a large number of invisible bacteria, viruses and other pathogenic microorganisms during the aggregation process, which may infect humans.
Therefore, it is not recommended to touch blue tears directly with bare limbs when viewing blue tears, especially if there are wounds on the limbs.
Blue tears are so beautiful.
Many friends want to bring blue tears home.
But this may not work, as noctilucent algae need to grow and thrive under conditions that can only be provided by specialized laboratories.
If you bring it home from the sea where the blue tears occurred, you may still see a little blue light that night, but after 2-3 days, the glow-in-the-dark algae will die, and you won't be able to see the blue tears.
