Signal crayfish can be found in habitats ranging from clear, shallow coastal streams (Lowery and Holdich 1988), to major rivers with high turbidity (Ibbotson and Furse 1995), as well as eutrophic and oligotrophic lakes and reservoirs (Holdich and Lowery 1988). After a month or more they hatch, forgoing a larval stage and looking, instead, like tiny adults. Crayfish also all wear the same costume, so to speaktheir exoskeletons are made of a tough chemical called chitin. Some of these so-called "terrestrial" crayfish dig water-filled tunnels that they inhabit in cooler months. Cambarellus diminutus of the south-eastern United States reaches only about 2.5 centimeters (1 inch) in length, while Astacopsis gouldi of Tasmania may reach 40 centimeters (15.7 inches) in length and weigh about 3.5 kilograms (8 pounds) (CC 2008).

The other studies confirmed that transporting crayfish to various environments has led to multiple ecological problems, including the native species elimination. Crawfish are a part of the Cajun culture dating back hundreds of years. Areas inhabited by the introduced crayfish also experienced dramatic decreases in benthic macroinvertebrate diversity (Girdner 2018). As heat waves become increasingly common, veterinarians call for extra vigilance.
