Crabs, the crustaceans that live in the ocean or fresh water, have attracted much attention for their unique morphology and rich biological characteristics. The production of crab specimens is not only to show its beautiful appearance, but also to study and protect these creatures.
Crabs have hard shells and often come in a variety of colors and patterns, allowing them to both camouflage and attract potential mates in their natural environment. In the process of specimen preparation, fresh samples need to be collected first. This often requires fishing in a variety of environments in order to obtain different species and states of crabs. Once captured, it is processed into a specimen, which goes through an elaborate dissection and fixation procedure to preserve its original form and color.
During the preparation of specimens, it is essential to examine the biological characteristics of crabs. The crab's body structure includes a horizontal carapace, characteristic pincers, and multiple pairs of feet, each of which contains a wealth of biological information. By observing and recording these characteristics, we can deeply understand their living habits, scientific research value and their role in the ecosystem.
The value of crab specimens is not only reflected in its research use, but also in the awareness of biodiversity conservation. With environmental changes and the impact of human activities, many crab species face threats to their survival. By producing and preserving specimens,biologists and conservation organizations are able to monitor endangered species while conducting educational campaigns to raise public awareness of this important ecological role.
In addition, crab specimens also play an important role in museums and educational institutions. They provide students with intuitive learning materials that enable people to better understand the complexity and mystery of Marine ecosystems.

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.
