This kind of thing used to be common in Beihai. In the 1990s, there was large-scale aquaculture along the beach of Baihutou. When people flocked ashore, the scene was really spectacular. However, in Baihutou and Longtan, no one has ever raised them. They used to raise washbasins as big as this. The taste is very strange, usually made of lemon, sweet and sour.

You're right. It's really old, even before dinosaurs. It is an "advanced" and "low-level creature". At the same time, all living things have evolved, even evolved into birds. Limulus is still a low-level marine life, and its evolution is not great.

The blood is really strong and blue. There is almost no uniqueness in the world today. As said upstairs, there are many other medical values. Their shells used to be used to make scoops, but now they can only be seen in remote rural areas near the sea. My grandmother is from Longtan. I have seen this in their house before. By the way, it seems that there are stalls hanging this thing in Nanzhu Market and Dacai Street behind Beizhong.

Hehe, I think it's a bit exaggerated to say that eating this is illegal and harmful to the environment. Now there is no one to eat in Beihai, because it is not difficult to catch, but there is very little to eat. Generally, it is also farmed, and it is not so serious to say that it is illegal. I'll tell you where to catch it. I often catch this thing myself. There are many, but they are all small. As big as half a slap, there are more smaller ones. There are many in the harbor at the junction of Baihutou and Daguansha, or on the beach in front of Daguansha mangrove forest. All you need to see is the shallow water area, with winding strips on it, and then you can see a lump of mud protruding from it, which is horseshoe crab. Just reach out and grab it. It won't bite you, and it runs slowly. Or you want to catch it, I'll take you to catch it on National Day, O(∩_∩)O~

I have a picture, too, but I took it myself, not online, O(∩_∩)O haha ~
