Sold in pails of 10. 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. 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.
