Freshwater Clam Specimen

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.
