Crab specimens are important tools for studying and displaying the biological characteristics of crabs. Crabs are Crustacea and are widely distributed in Marine, freshwater and terrestrial environments. Known for their rigid exoskeletons and strong pincers, they are an important ecosystem component.
The process of preparing a crab specimen consists of three main steps: catching, fixing and drying. First, the caught crab is quickly imfixed in a solution containing formaldehyde or alcohol to prevent its tissue from rotting. The fixed crab needs to be further dried, which can be done by natural air drying or using a desiccant. The drying process preserves the crab's original form and prevents deformation and decay.
After drying, the crabs are carefully placed in display boxes with information about their classification, where and when they were caught. Crab specimens not only provide valuable research materials for scientists, but also play an important role in education and display, helping the public understand the biological characteristics of crabs and their ecological role.
