The grassland crayfish is rather uniformly colored either bright red or reddish and has broad, powerful pincers. It inhabits prairies and grasslands from Wisconsin and Indiana down to Texas, including grasslands in northern and western Missouri.
This crayfish is gray with numerous greenish-black speckles and blotches on the pincers, carapace and abdomen. A pair of large blotches are present near the back of the head, and another pair occur near the junction of the carapace and abdomen. In our state, it is found only in the southeastern section.
This powerfully built crayfish is usually olive-tan or reddish brown, without prominent spots or blotches. A narrow blackish band is present at the junction of the carapace and abdomen. In our state, it is limited to the Ozarks of southern Missouri.
We’ve all seen aquariums and pictures of tropical saltwater invertebrates such as corals, jellyfish and anemones—but did you know that there are similar creatures living in the freshwater habitats of Missouri?
Over 30 Missouri species in former subclass Pulmonata
This is one of the two broad categories of aquatic snails in Missouri (the other is the gilled snails, or prosobranchs). Pulmonate snails breathe via a lunglike pulmonary cavity, and they lack a hard trapdoor-like operculum. Except for in the Ozarks, pulmonate snails predominate in most of the aquatic regions in our state.
This species has a very localized distribution: In our state, it's found only in the Warm Fork of Spring River, in Oregon County. This crayfish is reddish-brown and its broad, powerful pincers have numerous blackish specks on their basal parts.
