As a kind of unique Marine organism, sea urchin's morphology and ecological characteristics often attract the attention of biology lovers and scientific researchers. Belonging to the phylum echinoderm, sea urchins have hard shells and sharp spines, and their appearance presents a wide variety of shapes and colors, which make up their beauty and complexity. These specimens are not only of great value in scientific research, but also play an important role in the fields of art and education.
The outer shell of a sea urchin is a calcareous pentad structure,usually radially symmetrical. Its unique appearance makes sea urchins excellent specimen materials. After proper treatment and preservation after collection, specimens can maintain their original shape and color for a long time, which provides valuable information for the study of Marine ecosystems, species classification and biological characteristics
In the ecosystem, sea urchins play an important role. They are part of the seafloor food chain and maintain the ecological balance by eating algae and organic matter. The growth and reproduction cycles of sea urchins also provide rich information for scientific research. Sea urchins,for example, release eggs and sperm during the breeding season to form plankton,which goes through several stages before developing into juveniles,a process that is crucial to understanding the life cycle of Marine organisms.
From an educational point of view,sea urchin specimens provide students with intuitive learning materials. It helps students to understand the morphological characteristics of different Marine organisms and their strategies for adapting to the environment. In the classroom,by observing and studying the structure of sea urchins, students are able to better understand the basic concepts of taxonomy, ecology, and evolution of animals.
