The name "crayfish" comes from the Old French word escrevisse (Modern French écrevisse). [2] [3] The word has been modified to "crayfish" by association with "fish" (folk etymology). [2] The largely American variant "crawfish" is similarly derived. [2] Some kinds of crayfish are known locally as lobsters, [4] crawdads, [5] mudbugs, [5] and ...

The Everglades crayfish [2] (Procambarus alleni), 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.
The genus Cambarus is the second largest freshwater crayfish genus inhabiting the Northern Hemisphere, with only sixty fewer species than the genus Procambarus. [2] Though Cambarus are varied across species, the two terminal elements that make up the male form I gonopod form ninety degree angles with the central appendage, allowing for their identification.
Faxonius obscurus is a species of crayfish in the family Cambaridae. It is native to the northeastern United States, where it occurs in Maryland, New York, Ohio, Pennsylvania, Virginia, and West Virginia. It is an introduced species in adjacent regions, including Massachusetts, Vermont, and Ontario in Canada. [1]
Procambarus fallax (also known as deceitful crayfish [1] or slough crayfish [2] [4]) is a species of crayfish in the genus Procambarus. It lives in tributaries of the Satilla River in Georgia and Florida. [1] [2] It is the closest relative to the parthenogenetic marbled crayfish, Procambarus virginalis. [5] [6]
This crayfish was first described to science as a new species in 1987. [3] There has been little formal study of this species due to its rarity. [5]It has been postulated that the four subterranean crayfish species inhabiting the Ozarks, including Cambarus aculabrum, derive from a common epigean ancestor species that gained access to a historic cave channel in the Ozark Plateau.
Procambarus clarkii, known variously as the red swamp crayfish, Louisiana crawfish or mudbug, [3] is a species of cambarid crayfish native to freshwater bodies of northern Mexico, and southern and southeastern United States, but also introduced elsewhere (both in North America and other continents), where it is often an invasive pest.
