You and your students deserve the very best quality and safest preserved specimens available. With that objective in mind, Carolina Biological scientists and technicians developed a preservation formula that produces superior specimens while it also improves the safety of your classroom or lab. Our proprietary formula provides specimens that are: SAFE for you, your students, and the environment CONVENIENT to use and easy to dispose of SUPERIOR in tissue texture and color IDEAL for homeschool use Organisms preserved with Carolina's Perfect Solution® retain more lifelike 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 committment to producing the finest preserved specimens on he 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.

Here are just a few activities using the crayfish: Identify, remove, and examine the appendages along one side of a preserved crayfish, beginning at the anterior end Measure each of the appendages and have students compare the measurements in a graph or other format Investigate Molting Have students research the cultural and economic importance of crayfish and then write about a particular aspect of the research that interests them Assign younger students to write or read about crayfish

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.

Crayfish preserved and shipped in Carolina's Perfect Solution®, available in pails or in damp-packed vacuum bags.
