Common names: Ma shrimp, tiger shrimp, flower tiger shrimp, mud shrimp, shrimp, sand shrimp, red claw shrimp.
Origin and production period:
It is mainly distributed on the east coast of Japan, China's East China Sea and South China Sea, Philippines, Malaysia, Indonesia and Australia.
Introduction:
Light brown body, the upper edge of the forehead 6-9 teeth, no teeth on the lower edge. No central groove, the whip on the first tentacles is about 1/2 of the cephalothorax technique, and on the back of the abdomen is the longitudinal ridge on the back of the lth to 6th section. There is no lateral thorn in the tail section. The first pair of steps is full of thorns, and the last step has no external extremities. The new prawn's morphological characteristics are similar to those of the new prawn. The difference is that its abdomen swimming limb is bright red, the male cross-connector is “Y†shaped, the female cross-connector is “C†shaped, and the central plate is table-shaped.
A Microscope is an instrument used to see objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using such an instrument. Microscopic means invisible to the eye unless aided by a microscope.
There are many types of microscopes, and they may be grouped in different ways. One way is to describe the way the instruments interact with a sample to create images, either by sending a beam of light or electrons to a sample in its optical path, or by scanning across, and a short distance from the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses light to pass through a sample to produce an image. Other major types of microscopes are the fluorescence microscope, the electron microscope (both the transmission electron microscope and the scanning electron microscope) and the various types of scanning probe microscopes.
