Habitat Type: Freshwater
Comments: It is found in both permanent lentic and lotic situations such as ditches, marshes and lakes, and is a secondary burrower (Hobbs, 1989). Acosta and Perry (2002) suggest that this species is one of the most ubiquitous inhabitants of the seasonally flooded marl prairies wetlands of the eastern Everglades. Hobbs (1989) indicates that it is tolerant of a wide variety of parameters. Crayfish density was highest in habitats dominated by sawgrass in medium hydroperiod areas and spikerush in longer-hydroperiod habitat of the Evergladesm arl marshes (Acosta and Perry, 2002).
