The sea of sunlight and fluorescence lasted for several days.

Every April, the time is very short, that is, about 2 or 3 days. There are two kinds of fluorescence:

One is a continuous flashing green light spot;

The other is a blue light. In contrast, blue spots are more beautiful, but they are difficult to last.

There are many kinds of organisms that can glow in seawater, from unicellular dinoflagellate, such as luminous jellyfish, annelids, such as marine polychaetes, mollusks, such as various luminous cephalopods, and even arthropods, such as krill and fireflies.
