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.
Cambarus cryptodytes, the Dougherty Plain cave crayfish or Apalachicola cave crayfish, is a small, freshwater crayfish endemic to Florida and Georgia in the United States. It is an underground species known only from waters associated with the Floridan aquifer .
From 1964 until recent years, the Hell Creek Cave crayfish was only believed to exist in the cave system that is its namesake. [9] Yet in 2005, a second population of crayfish was found in Nesbitt Spring cave in the same county. Then in 2010, a third population was discovered at an upwelling near Town Branch River in Yellville, Arkansas. These ...
In 1990, Louisiana produced 90% of the crawfish in the world and consumed 70% of it locally, [13] but by 2003, Asian farms and fisheries produced more, outpacing American production rapidly. By 2018, P. clarkii crawfish production in the Americas represented just 4% of total global P. clarkii supply. [14]
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.
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 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]
A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves.These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors (subtroglophiles and trogloxenes).
