Preserved Earthworm Specimens for Dissection, Worm Dissection for Biology Classroom, Large 8-10 Inches, Vacuum Packed, 100 Pack

Ideal Introductory Dissection Specimen: Preserved Earthworm Specimens are excellent introductory dissection specimens for students. The earthworm is distinctive due to its lack of skeleton and its delicate, intricate structure. The preserved earthworm dissection specimen is large, measuring 8-10", making dissection simpler compared to other earthworm varieties. Hands-on Learning: Through specimen observation and dissection, students learn fundamental annelid anatomy and develop a better understanding of this invertebrate. Suitable for science students studying anatomy, biology, microbiology, and physiology. This earthworm specimen is a superb hands-on dissection specimen to prepare students for the handling skills required for more advanced dissection methods. Invertebrate Anatomy: Dissection is an effective teaching tool to learn about the complex organs and organ structures of the earthworm and how they compare to other higher invertebrates. Students will examine the unique characteristics of the earthworm such as the Clitellum, the digestive system that runs the length of the body, and a respiratory system that does not use typical respiratory organs. High-Grade Specimens: Preserved earthworms are processed by skilled technicians under strict quality control supervision with rigorous standards. Only specimens of good quality with a well-developed clitellum are selected. The earthworms for dissection are 8 to 10 inches in length and have no color injection (plain). Optimal Classroom Experience: Each specimen is intended for use by 1-2 students. The 10 packs of preserved Earthworm - Lumbricus specimens are moist vacuum packed and sealed in one or more heavy mylar-coated poly bags. The fixative process provides excellent preservation quality with low formalin odor and straightforward disposal, for a durable and more pleasant classroom experience
