Encased in a tough shell and armed with two large pincers it looks and indeed tastes rather like a freshwater Lobster or Langoustine and this is why I love to eat them..

I maschi, il cui peso può arrivare fino a 200 grammi, sono non solo più grossi ma anche decisamente più pesanti delle femmine, il cui peso non supera gli 80 grammi; inoltre possiedono chele più grandi. 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). This invasive species has brought disease to which our indigenous crayfish has no natural resistance. Its ability to tolerate water temperatures up to 33°C has allowed it to prosper in many environments. Pesticides should always be used in a lawful manner, consistent with the product's label. TWO men are reaping a fortune by catching thousands of American signal crayfish mini-lobsters from the River Thames. Larson ER, Olden JD, 2011. 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.

There is only one native crayfish species in Washington - the Signal crayfish (Pacifastacus leniusculus).This species can be identified by its uniform brownish coloration, white or light coloration of the claw joint ,and the smooth surface of its carapace and claws compared to that of nonnative species. Ackefors H, Lindqvist OV, 1994. They feed on fish and amphibian eggs, tadpoles, juvenile fish, aquatic invertebrates, detritus and aquatic vegetation and where present reduce populations of native species and affect food webs. Ironically, P. leniusculus, though resistant to crayfish plague, is a vector of the causal factor, and has been implicated in many plague outbreaks, which have seriously impacted native crayfish populations.
