Macrobranchium nipponense Life habits and morphological characteristics

The body is slender, and the whole body consists of two parts: the cephalothorax and the abdomen. The segments of the cephalothorax are connected, and the back and sides are covered by the thorax or carapace. The cephalothorax is thick, and the back gradually becomes thinner and narrower. The frontal horn is located in the center of the front part of the cephalothorax, with a straight upper edge and a sharp end. There is a sword-like protrusion at the front of the carapace, 11 to 15 teeth on the upper edge, and 2 to 4 teeth on the lower edge. The body surface has a hard shell, and the whole is composed of 20 segments, 5 segments on the head, 8 segments on the thorax, and 7 segments on the abdomen. There are 5 pairs of walking legs, 2 pairs of which are pincer-shaped, and the last 3 pairs are claw-shaped. The appendages of the 6th abdominal segment have evolved into a powerful tail fan, which plays a role in maintaining the balance of the shrimp body, lifting and retreating.

After obtaining, wash and use fresh or dry them for later use. The larger ones can be steamed and peeled for use, also known as dried shrimp.

6. Shrimp contains protein, fat, vitamins A, B1, B2, niacin, calcium, phosphorus, iron and other ingredients.

7. Intravenous injection of shrimp meat extract in dogs can increase the protein concentration in lymph, reduce coagulability, significantly increase the lymph flow in the cerebral duct, and show adenosine phosphate (ATP) in plasma, but no significant increase in histamine.
