Perfect Solution 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. Color Injection: Plain: No color injection. Single: Circulatory system injected with colored latex. |
