Razor clam shells, black edge can not be eaten, the picture is as follows:

1, razor clam shells

Razor clam shells can not be eaten, we all know, on the one hand, because of razor clam shells of the texture of the very hard, should not be eaten; on the other hand, because of the razor clam shells of the nutrients in the limited, food value is not high.

2, razor clam black edge

In the razor clam shell outside a circle of black edge, this is also generally not recommended for consumption, because of which with more sediment and bacteria and other microorganisms. The black mass inside the razor clam's stomach is sediment, undigested food, feces, intestinal glands and some internal organs, so it's not all feces, and occasionally there is undigested food that the razor clam has not yet digested after it has just eaten. The black parts inside the stomach of razor clams may be feces, or sand, internal organs, etc., but it is mainly the visceral mass, so razor clams can be eaten directly after spitting out the sand.

Life habits of razor clam

The two water pipes of razor clam are very well developed, and it completely relies on them to keep in touch with the seawater on the beach, sucking in food and fresh seawater from the inlet pipe, and discharging wastes and effluents from the drain pipe. The razor clam lives in a dugout on soft mud flats, and the depth of lurking varies with the seasons: in warm summers, the lurking is shallower; in cold winters, the lurking is deeper. Normally, the depth of lurking is about 5 to 6 times the length of the body, and the deepest can reach 40 centimeters, which is about 10 times the length of the body.

If we see two small holes not far from each other on the beach, with a long hook to touch a little seawater can be sprayed out, then there must be underneath the razor clam. These two holes are where the two water pipes of the razor clams stick out. The size of the razor clam can be deduced from the distance between the two holes, and its body length is about 2.5 to 3 times the distance between the two holes.
