Crab is a kind of crustacean living in Marine or freshwater environment. Because of its unique morphology and ecological habits, it has become an important object in biological research. In museums or scientific research institutions, crab specimens often appear on exhibition counters, attracting the attention of researchers and the public.
The process of preparing crab specimens is rather complicated, so it is necessary to have a certain understanding of the preservative technology of biological specimens. First, caught crabs need to undergo initial treatment, including cleaning and gutting. It is then treated with preservatives to prevent rot and insect infestation. Commonly used preservatives include formaldehyde solution, etc., to maintain the stability of its structure and color.
In the process of specimen preparation, researchers also need to accurately record the morphological characteristics of the crabs. This includes its shell color, texture, body proportion, etc., which are important bases for studying the classification, ecology and physiological characteristics of crabs. By looking at these features, scientists were able to identify different species of crabs and understand their role in the ecosystem.
Specimens are usually displayed with detailed labels indicating the species name, time and place of collection, and relevant ecological information. This allows visitors not only to appreciate the beauty of the crab's appearance, but also to gain an in-depth understanding of its living habits and environmental needs.
In scientific research, crab specimens provide valuable data for many fields. Ecologists study the effects of crabs on aquatic ecosystems by analyzing their position in the food chain. Biologists can explore their physiological structure and evolutionary processes to further understand the diversity of crustaceans.

In nature, the crab is a very fascinating Marine creature, and its unique form and rich ecological habits have attracted wide attention from scientists and enthusiasts. Although crabs inhabit a variety of habitats, their common characteristics are a pair of strong pincers and a flat body, which can move freely in the sediment or rock crevices. In order to better study and understand these organisms, the preparation process of crab specimens is particularly important.

The preparation of crab specimens usually requires the selection of a suitable sample first. The preservation of specimens helps to show their external characteristics, anatomical structure and ecological adaptability. After catching crabs, they are usually treated immediately to ensure their morphological integrity. First, the captured crabs are washed to remove attached sediment and impurities, and then pickled or mellowed to prevent decay. Common preservative fluids include formaldehyde and alcohol, which can effectively inhibit the growth of bacteria and fungi.

In the process of specimen preparation, parts such as the limbs, pincers and eyes of the crab need to be carefully observed and recorded. The scientists will record information about the crabs' feeding habits, habitat and breeding behavior to provide reference data for future studies. After specimen preparation, the external characteristics of the crab can be displayed to the public through transparent containers for educational and research use. This will not only help students and researchers intuitively understand the biological characteristics of crabs, but also improve the public's awareness of Marine ecological conservation.

In addition, with the development of science and technology, digital technology is playing an increasingly important role in specimen production. Some research institutions are beginning to try to combine three-dimensional models of crabs with traditional specimens.

As an important part of the Marine ecosystem, crabs are favored by many biological enthusiasts for their unique appearance and diverse species. Crab taxidermy is not only a fun hobby, but also an important tool for scientific research and education.

A specimen of a crab shows the anatomy and life characteristics of the creature, and its form is usually fixed by professional taxidermy methods. First, caught crabs need to be cleaned and disinfected to ensure that surface impurities and microorganisms are removed. Then, it is put into a fixed solution, commonly formalin or alcohol solution, so that it can effectively prevent the growth of bacteria and keep its form stable.

During the immobilization process, the details of the crab's limbs, pincers and shell require special attention. These parts are the core of survival and feeding of crabs, and understanding their structure is helpful to study their living habits and ecological functions. In order to better display the specimen, you can choose to place it in a transparent display box, and provide details such as scientific classification information, habitat and environment of the organism through the specimen label.

Crab specimens are of great value in teaching and scientific research. They provide students with the opportunity to observe and learn, helping them understand the complexity of ecosystems and the interrelationships between species. In the field of scientific research, the existence of specimens also provides biologists with important physical data for population studies and ecological assessments.

With the enhancement of people's awareness of Marine ecological protection, the display of crab specimens is often integrated into the theme of environmental protection. The ecological knowledge behind the specimens can promote the public's understanding of Marine biodiversity, thereby enhancing support for environmental protection.
