You and your students deserve the very best quality and safest preserved specimens available. Organisms preserved with Carolina's Perfect Solution® retain more life like color and texture. Because students study more natural-looking specimens, it's easier for them to identify the structures and, as a result, learn anatomy. Our commitment to producing the finest preserved specimens on the market has led us to Carolina's Perfect Solution®, a unique, revolutionary fixative that is changing the process of preserving specimens and is dramatically improving the quality of classroom dissection. Carolina's Perfect Solution® specimens are also ideal for homeschool use. The specimens are safe and nontoxic, which means you need no special ventilation and there's no costly disposal. Disposing of preserved specimens and preservation fluids after use isn't complicated, but does require some thoughtful planning. Click Here for Disposal Guidelines.

Crayfish are members of the phylum Arthropoda (commonly called arthropods) and the class Crustacea. Because of their very specialized - diverse yet similar - appendages, crayfish are the perfect specimens to convey to students the relationship between structure, function, and the environment.

Use crayfish to address National Science Education Standards on Structure and Function in Living Systems; Matter, Energy, and Organization in Living Systems; and the Behavior of Orgasnisms.
