Discover the fascinating world of marine biology with this real, preserved sea urchin specimen, expertly prepared and sealed for long-term educational use. This authentic echinoderm specimen provides students and educators with a hands-on opportunity to explore invertebrate anatomy, including the test (shell), spines, tube feet, water vascular system, Aristotle's lantern (feeding apparatus), and internal organ systems commonly studied in laboratory dissections. Preserved in formalin and maintained in solution, the specimen retains key anatomical features for accurate observation, making it ideal for classroom, laboratory, and homeschool learning environments. Key Features: Authentic preserved sea urchin specimen for hands-on learning Professionally prepared and sealed for safe classroom and laboratory use Allows detailed study of echinoderm anatomy, including test, spines, tube feet, water vascular system, and internal organs Preserved in formalin for long-lasting durability and repeated educational use Securely packaged to ensure specimen integrity during storage and transport Benefits: Enhances marine biology, anatomy, and ecology lessons with real specimen study Ideal for dissections, science classrooms, homeschool curricula, and lab demonstrations Supports instruction in invertebrate zoology, echinoderm biology, and comparative anatomy Provides students with an interactive, hands-on learning experience Maintains structural detail for reliable observation over time Educational Insight: Sea urchins are echinoderms known for their radial symmetry, spiny defenses, and unique hydraulic movement system. Studying sea urchin anatomy helps students understand echinoderm body plans, feeding mechanisms, locomotion via tube feet, and evolutionary adaptations within marine ecosystems. What's in the Package: One preserved sea urchin specimen, approximately 2–3 inches in size, sealed and ready for classroom, laboratory, homeschool, or museum use.
