The State Invertebrate

On June 21, 2007, the crayfish (also known as crawfish and crawdad) became the official state invertebrate. Crayfish are an important food source for Missouri fishes. Missouri supports more than 30 species of crayfish (including seven species that occur nowhere else in the world). Crayfish are found in every county of the state and contribute to our unique biodiversity and conservation heritage. The nomination of crayfish for state invertebrate came from Mrs. Janna Elfrink's elementary school class in Reeds Spring, Missouri. (RSMo 10.125)
