Plain Preserved Clam Dissection Specimen for Biology Labs | Bivalve Mollusk Anatomy
This plain preserved clam dissection specimen is an excellent educational specimen commonly used in middle school and high school biology labs to teach bivalved mollusk anatomy and basic invertebrate classification. Clams are a classic model organism for anatomy studies because their simple body plan clearly demonstrates how bivalves feed, breathe, and move. Each specimen measures approximately 3 to 4 inches across and is preserved to maintain clear visibility of anatomical structures, making it ideal for hands-on classroom dissection. Students begin by examining the external anatomy of a clam, then proceed to explore the internal anatomy of a bivalve mollusk during dissection.

This preserved clam specimen for dissection supports instruction in invertebrate biology, marine science, and comparative anatomy, making it an excellent choice for anatomy labs, life science courses, and homeschool science programs. Pair it with a clam dissection kit that includes tools, a dissecting guide, and a tray for a complete lab experience. Specimens are initially fixed using a formaldehyde solution to preserve tissue structure, then rinsed and stored in a glycol-based solution, producing a moist, low-odor, long-lasting specimen suitable for educational use.
Did You Know? Clams do not have a head or eyes, yet they can sense changes in their environment using specialized cells along their mantle. Their powerful adductor muscles allow them to snap their shells shut tightly, helping protect them from predators and drying out when exposed at low tide.
