The gecko is a common small reptile belonging to the lizard family. They are usually small, ranging from a few centimeters to a dozen centimeters in length, and their bodies show a variety of colors and patterns to adapt to different living environments. Specimens of geckos are often used for biological research and educational purposes, providing an opportunity to observe the characteristics and behavior of these creatures.

What makes geckos unique is their ability to stick. Geckos have many small hairs on the soles of their feet, called "surface fur". These hairs interact with the surface through van der Waals forces, allowing the gecko to walk freely on a vertical wall or ceiling without slipping. This unique adaptation gives geckos a great advantage when hunting insects, and it has also become a hot spot for scientific research, potentially providing inspiration for the development of biomimetic materials in the future.

During the preparation of specimens, geckos are usually preserved in their complete form to capture their biological characteristics for easy research and teaching. Preparation of the specimen generally includes laparotomy, peeling, and preserving its shape and color with appropriate fixatives. Through these steps, specimens of geckos can be preserved for a long time and provide the opportunity to observe their anatomy, muscle orientation, and other physiological features.

In educational Settings, gecko specimens are used to help students understand the importance of biodiversity and ecological balance. By observing the morphology and living habits of geckos, students can more clearly understand their role in the ecosystem. At the same time, the specimen also raises concerns about the conservation of reptiles and their habitats, and educates people to respect and value nature.
