== Description ==
The genus ''Cambarus'' is the second largest freshwater crayfish genus inhabiting the Northern Hemisphere, with only sixty fewer species than the genus ''[[Procambarus]]''<ref name=":0" />. 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. Unlike the genus ''[[Procambarus]]'' whose first [[pleopod]] tends to have three processes at the tip, ''Cambarus'' has only one or two<ref name=":0">{{Cite book|title=Biology and Ecology of Crayfish|last=Longshaw|first=Matt|publisher=CRC Press|year=2016|isbn=9781498767323|location=New York|pages=17–18}}</ref>. ''Cambarus'' reach 17-26 mm [[carapace]] lengths in their first year, while average adult carapace length ranges from 55-62 mm<ref name=":3" />.

As a genus containing nearly 100 species, ''Cambarus's'' coloration is variable<ref name=":4" />. [[Cambarus bartonii|''Cambarus bartonii'']] is dark brown, while species like ''[[Cambarus pauleyi]]'' range from subtle to vibrant blues and reds<ref name=":0" />. 

== Biogeography ==
Most species of ''Cambarus'' are distributed along North America's eastern coast, extending from [[New Brunswick]] to northern Florida<ref name=":0" />. However, the genus extends as far westward as the [[Rocky Mountains]] of Wyoming and Colorado, inhabiting a variety of [[Fresh water|freshwater]] environments<ref name=":1">{{Cite web|url=http://eol.org/pages/313082/details|title=Cambarus diogenes|last=Cordeiro|first=J.|date=2014|website=Encyclopedia of Life|archive-url=|archive-date=|access-date=March 29, 2018}}</ref>. Devil crayfish (''[[Cambarus diogenes]])'' are perhaps the most widespread species in the genus, having been found in thirty states spanning approximately 2 million kilometers<ref name=":1" />. Though, most species of ''Cambarus'' are not so widely distributed<ref name=":3" />.

=== Habitat ===
''Cambarus'' occupy a range of freshwater environments including streams, rivers, lakes, and burrows. Burrowing species of the genus include ''[[Cambarus dubius]]''<ref name=":0" />. ''Cambarus'' also include many cave-dwelling species, both [[List of troglobites|troglobites]] and [[Troglofauna|troglophiles]]<ref name=":3" />. While salinity and temperature changes minimally affect ''Cambarus'', the genus has shown an intolerance to [[Anthropogenic climate change|anthropogenic]] pollution<ref name=":2">{{Cite journal|last=Buhay|first=J et al.|date=February 2007|title=Molecular taxonomy in the dark: Evolutionary history, phylogeography, and diversity of cave crayfish in the subgenus Aviticambarus, genus Cambarus|url=https://www.sciencedirect.com/science/article/pii/S105579030600279X|journal=Molecular Phylogenetics and Evolution|volume=42|issue=2 |pages=435–448|doi=10.1016/j.ympev.2006.07.014 |pmid=16971141 |via=ScienceDirect}}</ref>.

== Ecology ==
=== Diet ===
Like other crayfish, ''Cambarus'' are foragers. Diets are largely plant-based, though ''Cambarus'' also consume small marine organisms like molluscs, larvae, tadpoles and amphibian eggs. ''Cambarus'' also consume small rodents or birds when available<ref name=":3" />. In their first year, ''Cambarus'' typically consume 1-4% of their overall body-weight each day <ref name=":3">{{Cite book|title=Biology of Freshwater Crayfish|last=Holdich|first=David M.|publisher=Blackwell Science|year=2002|isbn=0-632-05431-X|location=London|pages=609–613}}</ref>. The genus is central to many freshwater [[Food web|food webs]] as they help maintain water quality through consumption of [[algae]]<ref name=":2" />.

=== Vulnerability ===
One of the largest crayfish genera, ''Cambarus'' includes a sizable number of vulnerable species <ref name=":2" />. Cave-dwellers like ''[[Cambarus jonesi]]'' are at risk due to their lack of [[genetic diversity]] and low population count. Other species like ''Cambarus veteranus'' are at risk due to human practices like logging and mining, which increase sediment amounts in freshwater environments<ref name=":0" />. 

== Behavior ==

=== Growth ===
[[Moulting]] occurs among ''Cambarus'' approximately 5-10 times during their first year, and 3-5 times during subsequent years. ''Cambarus'' remain relatively inactive during periods of moulting, as the shedding of [[chitin]] [[Exoskeleton|exoskeletons]] leaves them more vulnerable to predation and injury<ref name=":3" />.

=== Reproduction ===
''Cambarus'' typically mate in the early spring. Both ''[[Cambarus bartonii|Cambarus batonii]]'' and ''Cambarus robustus'' only mate once during their three year life span, with females of both carrying fewer eggs than those of the ''[[Orconectes]]'' genus<ref name=":3" />.
