Do crabs live in the Arkansas River?

Crabs are not native to the Arkansas River, as they primarily inhabit saltwater or brackish environments. However, some freshwater species, like the freshwater crab, can be found in various freshwater habitats. It's important to note that while crabs are generally associated with coastal areas, certain species may adapt to freshwater environments in other parts of the world. In the case of the Arkansas River specifically, you are unlikely to find crabs.
