Hello friends!Sea shrimp and freshwater shrimp are two common shrimp species that differ in appearance, habits, and nutrients. This article will conduct a professional linguistic analysis of marine shrimp and freshwater shrimp from the following aspects to help readers identify these two types of shrimp.
1.Appearance features
There is a certain difference in appearance between sea shrimp and freshwater shrimp. First of all, in terms of color, the color of sea shrimp is usually bright, such as red, blue, green, etc., while the color of freshwater shrimp is relatively simple, mainly blue-gray or brown. Secondly, in terms of body size, sea shrimp are larger in size and generally between 5-20 cm in length, while freshwater shrimp are smaller in size and generally between 2-5 cm in length. Also, the sea shrimp has longer antennae and is whip-shaped, whereas the freshwater shrimp has shorter antennae and is hooked. Finally, from the carapace, the carapace of the shrimp is harder and has more unevenness on the surface, while the carapace of the freshwater shrimp is softer and the surface is smoother.
2.Habits
Marine shrimp and freshwater shrimp also differ in their living habits. Sea shrimp live in the marine environment and need to cope with various changes in tides, salinity, temperature, etc., so they have strong adaptability. Freshwater shrimp live in freshwater environments such as rivers and lakes, which have high requirements for water quality and relatively weak adaptability to the environment. In addition, there are differences between marine shrimp and freshwater shrimp in their way of reproduction. Shrimp reproduce oviparously, with females laying eggs on their abdomen and males fertilizing after females have laid eggs. Freshwater shrimp reproduce viviparously, and female freshwater shrimp will hatch fertilized eggs in the body to produce juvenile shrimp directly.
3.Nutrition facts
There are also certain differences in nutrient composition between marine shrimp and freshwater shrimp. Sea shrimp are rich in a variety of nutrients such as protein, fat, minerals, and vitamins, with a higher protein content and a lower fat content. Whereas, freshwater shrimp has a similar nutrient composition to marine shrimp but is slightly different in some ways. For example, freshwater shrimp has a high content of minerals, especially minerals such as calcium and phosphorus, which have a good effect on the development of human bones and teeth. In addition, freshwater shrimp are high in vitamin B12, which helps to maintain the normal function of the human nervous system.
4.Cooking method:
Due to the differences in taste and nutrient content between marine and freshwater shrimp, there are also differences in cooking methods. The meat of sea shrimp is delicious, and it is suitable for steaming, boiling soup, stir-frying and other cooking methods. Freshwater shrimp is more delicate and tender, which is more suitable for simple cooking methods such as steaming and boiling soup to retain its original flavor.
In summary, by observing the characteristics of marine shrimp and freshwater shrimp in terms of appearance, living habits, nutrients and cooking methods, we can accurately identify these two types of shrimp. However, it should be noted that due to the existence of some counterfeit and shoddy products on the market, it is necessary to make a comprehensive judgment when purchasing.
