The Teays River (pronounced taze) was a major preglacial river that drained much of the present Ohio River watershed, but took a more northerly downstream course. Traces of the Teays across northern Ohio and Indiana are represented by a network of river valleys. The largest still existing contributor to the former Teays River is the Kanawha River in West Virginia, which is itself an extension of the New River. The name "Teays," from the much smaller Teays Valley still extant above the surface, has been associated with the river and the remainder of its related buried valley since 1910. The more appropriate name would be the Ancestral Kanawha Valley. The term Teays is used when discussing the buried portion of the Ancestral Kanawha River. The Teays was comparable in size to the Ohio River. The River's headwaters were near Blowing Rock, North Carolina; it then flowed through Virginia, West Virginia, Ohio, Indiana, and Illinois.. The largest tributary to the Teays River was the Old Kentucky River, which extended from southern Kentucky through Frankfort and subsequently flowed northeast, meeting other tributaries and eventually joining the Teays.

The Everglades crayfish, sometimes called the Florida crayfish, the blue crayfish, the electric blue crayfish, or the sapphire crayfish, is a species of freshwater crayfish endemic to Florida in the United States.

Populations are often mistaken with Cambarus veteranus, but morphological and genetic data suggest that these are separate taxa; however, both are protected under the Endangered Species Act. There is very little information available on the Big Sandy crayfish because it is a relatively new species.
