In acqua questo crostaceo sistema egli stesso il suo spazio vitale: sotto grosse pietre o nelle cavità formatesi fra radici, anche se esso non mantiene necessariamente una sua tana abituale, ma dopo la ricerca del cibo può scegliere la sua sistemazione in una cavità diversa da quella da cui è uscito per la ricerca.

(2014) have also demonstrated an increased density and resilience to control of invasive non-native mammalian carnivore populations such as the American mink, Neovison vison, in ecosystems with established invasive non-native crayfish populations, due the availability of a superabundant prey item. Native crayfish species are frequently replaced due to having lower fecundities (Eng and Daniels, 1982), an inferior ability to compete for shelter leading to an increased susceptibility to predation (Dunn et al., 2009), vulnerability to reproductive interference leading to diminished recruitment (Westman et al., 2002) or due to being directly predated upon (Nataka and Goshima, 2006). The characteristic 'signal' markings can be observed on the claws. Summary of Invasiveness Top of page.
