The greatest diversity of crayfish species is found in southeastern North America, with over 330 species in 15 genera, all in the family Cambaridae. A further genus of astacid crayfish is found in the [[Pacific Northwest]] and the headwaters of some rivers east of the [[Continental Divide]]. Many crayfish are also found in lowland areas where the water is abundant in [[calcium]], and oxygen rises from underground springs.<ref>{{cite book |author = Steve Pollock |title = Eyewitness Ecology |location = [[New York City|New York]], [[United States]] |publisher = [[Dorling Kindersley]] |year = 2005 |isbn = 978-0-7894-5581-9 |url-access = registration |url = https://archive.org/details/eyewitness00stev }}</ref> Crayfish are also found in some non-coastal wetlands; eight species of crayfish live in [[Iowa]],<ref>{{Cite press release |title=What's a Mudbug? |date=2022-07-12 |publisher=[[Iowa Department of Natural Resources]] |url=https://www.iowadnr.gov/About-DNR/DNR-News-Releases/ArticleID/4127/What-39-s-a-Mudbug}}</ref> for example.
