The difference between tiger prawns and shrimps

Tiger shrimp

The tiger prawn is commonly known as the black tiger prawn, ghost prawn, grass prawn, flower prawn, and bull-shaped prawn. The Food and Agriculture Organization of the United Nations generally calls it the giant tiger prawn. Its body is covered with black-brown and earthy yellow horizontal stripes. There are 7 to 8 teeth on the upper edge of the frontal horn and 2 to 3 teeth on the lower edge. The lateral groove of the frontal horn is quite deep, extending to the back of the eye spine, but the lateral ridge of the frontal horn is low and blunt, and the central groove of the rear ridge of the frontal horn is obvious. There is a distinct liver ridge and no frontal gastric ridge.

In addition to being the same as ordinary shrimp, the content of astaxanthin in tiger prawns is about 20% higher than that of ordinary shrimps, so the price is relatively high during the Spring Festival. Astaxanthin is the strongest antioxidant, which can significantly enhance the survival rate and spawning rate of shrimps, as well as their ability to resist the harsh external environment. Similarly, eating shrimp meat high in astaxanthin can significantly improve diseases such as atherosclerosis in humans and animals.

Shrimp

The shrimp, also known as "unicorn shrimp", belongs to the class of soft armor, family of Penaeidae. It is about 8cm long, with many concave parts on the body surface, on which short hairs grow. The frontal horn is straight, with only 7-9 teeth on the upper edge. The cephalothorax has obvious cardiobranchial grooves and cardiobranchial ridges, obvious hepatic grooves, hepatic spines, antennal spines and supra-ocular spines, and no cheek spines. The first three pairs of walking legs have basal spines, the first leg has a sacral spine, the fifth walking leg has no external limbs, the seventh thoracic segment has lateral gills, and the third jaw has no limb gills. It is an important economic species and is the object of artificial breeding.

Prawns are rich in nutrients, with soft texture and easy to digest. They are excellent food for people who are weak or need recuperation after illness. Prawns are rich in magnesium, which can protect the cardiovascular system very well. It can reduce the cholesterol content in the blood, prevent arteriosclerosis, and dilate the coronary arteries, which is beneficial for preventing hypertension and myocardial infarction.
