There are 2 body segments, 5 head segments, 8 chest segments and 7 abdomen segments. It is called "exoskeleton" because it is covered with chitin shell to protect internal organs and fix muscles. The carapace of the head and chest is an unsegmented whole, called the head breastplate, and the front end of the head breastplate protrudes forward with a sharp frontal angle. The frontal angle of freshwater shrimp is relatively straight, and the upper and lower edges of the frontal angle have neatly arranged serrations, which are called frontal teeth. The number of teeth is a characteristic of classification. The abdominal nail remains segmented. There are soft membrane connections between the front and rear armor and between the head and chest armor and the abdominal armor, which can make the body bend freely. Except the tail segment, the last segment of the abdomen, each segment has L pairs of appendages. The appendages of different parts are specialized into various shapes because of their different functions. The five pairs of appendages of the head are transformed into the first and second antennae respectively, which are olfactory and tactile organs, and the big jaw and the first and second small jaws form the mouthparts. There are 8 pairs of appendages in the chest, and the first 3 pairs are the first, second and third jaw feet, which are also part of the mouthparts and are feeding organs. The last five pairs of appendages are gait, in which the ends of the first and second pairs of gait are pincers, and the second gait is stronger and stronger, especially the male shrimp. The ends of the last three pairs of feet are single-claw. All abdominal segments except caudal segment have L pairs of appendages. Six pairs of appendages are bipedal, and the first to fifth pairs are flat and pulpy, which are called gastropods, and have the functions of swimming, jumping and holding eggs. The sixth pair of appendages spread backward and form a tail fan with the caudal segment, which has a balanced orientation function when swimming. There are 1 pair of rehabilitation clothes at the front end of the head and chest and on both sides of the base of the frontal angle, which can rotate freely.
