Crab specimens are important samples for the study of Marine life and are often used for scientific classification, ecological research and educational displays. There are more than 6,000 species of crabs worldwide, which can be divided into freshwater, saltwater and land crabs depending on their habitat. They play a key role in Marine ecosystems, participating in the food chain and maintaining ecological balance.
The process of preparing a crab specimen involves catching, fixing and preserving it. Once caught, crabs usually need to be fixed on their carapace to ensure that they are in good shape. The specimen is then treated with a preservative such as ethanol or formalin to prevent decay. Complete specimens not only facilitate researchers to observe their anatomical characteristics and behavior habits, but also provide the public with a window to understand Marine life.
In addition, the display of crab specimens often uses artistic techniques to combine science and aesthetics, attracting more people to pay attention to Marine conservation and biodiversity. Through these specimens, we are able to gain a deeper understanding of the complexity and vulnerability of Marine ecosystems.
