Orconectes
''Orconectes'' is a genus of cave dwelling freshwater crayfish, endemic to suitable habitats in the eastern United States. Surface dwelling species, formerly categorised here, were moved to ''Faxonius'' in 2017. Due to their subterranean habitat, they are usually depigmented, often blind, and are long-lived. Ages of 176 years have been claimed for ''O. australis'', though this was reduced to ≤22 years in a 2012 study. Taxonomy The genus ''Orconectes'' was erected in 1872 by Edward Drinker Cope to house ''Astacus pellucidus'' (now ''Orconectes pellucidus'') and his new species, ''Orconectes inermis''. Prior to the 2017 review by Oxford university, the genus contained 85 species in 11 subgenera. The ''Faxonius ''Faxonius'' is a genus of freshwater crayfish in the family Cambaridae. There are more than 90 described species in ''Faxonius''. It includes the rusty crayfish, an invasive species in North America, and three species, ''F. virilis'', ''F. immu ...'' subgenus was ...

List Of Troglobites
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). Land-dwelling troglobites may be referred to as troglofauna, while aquatic species may be called stygofauna, although for these animals the term ''stygobite'' is preferable. Troglobites typically have evolutionary adaptations to cave life. Examples of such adaptations include slow metabolism, reduced energy consumption, better food usage efficiency, decrease or loss of eyesight (anophthalmia), and depigmentation (absence of pigment in the integument). Conversely, as opposed to lost or reduced functions, many species have evolved elongated Antenna (biology), antenna and Leg, locomotory appendages, in order to better move around and respo ...

''Faxonius'' is a genus of freshwater crayfish in the family Cambaridae. There are more than 90 described species in ''Faxonius''. It includes the rusty crayfish, an invasive species in North America, and three species, ''F. virilis'', ''F. immunis'', and ''F. limosus'', that are invasive to Europe. This genus was formerly considered a subgenus of ''Orconectes''. Several former ''Orconectes'' species were added to this genus in 2017, leaving only the cave dwelling species unchanged, however ''F. stygocanei'' was reallocated, even though it lives in caves.

Crayfish
Crayfish are freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. In some locations, they are also known as crawfish, craydids, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, baybugs or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as ''Procambarus clarkii'', are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus. The term "crayfish" is applied to saltwater species in some countries. Terminology The name "crayfish" comes from the Old French word ' (Modern French '). The word has been modified to "crayfish" by association with "fish" (folk etymology). The largely American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
