In the morning, I saw a tweet:
Well, there is another thing about eating clams and eating crystal rods as bugs
Oh, why did I say again?
Someone else made a video before:
There is a lot of news about searching the Chinese network and treating clams as parasites. Other shellfish are rare.
So, what is the crystal rod?
The rod is a normal and necessary organ in the digestive tracts of molluscs such as flap gills (i.e., bivalve shellfish) and gastropods (i.e., conchs, snails, etc.), and it is a translucent gelatin-like rod body full of digestive enzymes. You can think of this thing as a stick-shaped "ink ingot" in the stomach of these two types of mollusks, which rotates while colliding with a hard structure (chitin gastric shield) in the middle of the stomach during digestion, releasing digestive enzymes.
A study of ctenophores scallops showed that the rod contains polysaccharides, mucopolysaccharides or mucins, proteins, and glycase to digest food. The rod itself is not an organ that secretes digestive enzymes. But it can collect and store digestive enzymes, which are slowly released during digestion, and have the function of mechanical digestion.
Let's look at the rods of other shellfish:
This is the crystal rod of the Pacific mud clam. Some people abroad think that this thing is the penis of the Pacific mud clam, but the mud horse Pacific mud clam body is more like a penis (search for your own picture). Image credit: chezshinae.blogspot.jp
What kind of sea mantis clam (myasp.) crystal rod is this, isn't it very beautiful? The buddies from www.stripersonline.com who sent this picture also thought it was a parasite.
In the above post, a netizen who replied to the post provided a picture that looked more majestic:
This is the netizen in the Bahamas filmed. This is the crystal rod of a large conch. Locals think it's a conch's penis, and then eating it can be aphrodisiac. Well, here's how they ate:
It is said to be a bit salty to eat.
As for whether the crystal rod can be eaten, well look at the above and you will know that you can eat it. Domestic fishery professionals will tell you that you can eat, while foreign cooking tutorials will say to get rid of it. This difference is mainly in the Chinese encounter crystal rod is mainly on the clam, the chip rod of the clam is not large or hard, the type of crooked nuts is different, and the cooking method is also different.
Just the sauce.
