The beard and the nose are hooked, the back bow is in a node shape, and the tail part is provided with hard scale feet which are good for jumping. Many are important foods. The size is from several meters to several millimeters, and the average size is 4-8 centimeters. The large size is called prawn. The abdomen and the tail can be quickly bent to swim. Eating micro organisms, some eating rotten meat. Female shrimps can lay 1,500-14,000 eggs and are attached to swimming limbs. 5 developmental stages are required before adulthood. Its seed is outside the abdomen, and the taste is very fresh, people like to eat. The shrimp is long and flat, the exoskeleton is made of calcareous material and is divided into a head part, a chest part and a belly part. The cephalothorax is covered by the carapace. The abdomen is composed of 7 segments. The front end of the skull is provided with a frontal sword with a long tip and a zigzag shape and 1 pair of rotatable compound eyes with handles. The shrimp breathes on the branchia, which is located on both sides of the head and chest and covered by the shell. The mouth of the shrimp is at the bottom of the cephalothorax. There are 2 pairs of tentacles in the head and chest, responsible for olfaction, touch and balance, and there are also masticatory consisting of large and small jaws. There are 3 pairs of jaw feet on the head and chest to help hold food, and 5 pairs of foot feet, mainly used for predation and crawling. The abdomen has 5 pairs of swimming limbs and a pair of thick and short tail limbs. The last section of the tail limb and the abdomen is combined into a tail fan which can control the swimming direction of the shrimps. The motion organs of the shrimps are not developed, and the shrimps can only slowly crawl on the seabed at ordinary times and can swim for a short distance by utilizing the flexion and extension action of the abdomen of the body. Modern medical research proves that the shrimp has extremely high nutritive value, and can enhance the immunity and sexual function of human bodies, tonify kidney, strengthen yang and resist premature senility. Eating fresh shrimp often, taking with warm wine, can be used for treating kidney deficiency, sexual impotence, aversion to cold, tiredness, soreness of waist and knees, etc. Therefore, the industrial development of the shrimp larvae is driven, the shrimps are easy to be killed if the shrimp larvae are not professional technical operation, the shrimps are benthonic animals, the pond bottom environment is the basis of the whole growth environment of the shrimps, and the detection of the shrimps is also very important when the water quality is treated.
