''Orconectes immunis'', the calico crayfish or papershell crayfish, is a species of North American freshwater crayfish which has also been introduced to Europe, where it lives along the Upper Rhine. It lives in slow-flowing bodies of water, and can survive by burrowing if they dry out. ==Description== ''Orconectes immunis'' is similar to a number of other species of crayfish in the genus ''Orconectes''. While the colouration of the claws is distinctive, it can be difficult to use that to identify a specimen without reference specimens for comparison. ''O. immunis'' can be distinguished from ''O. virilis'' by the presence of a notch near the base of the ''dactylus'' (finger) of the claw, which is not found in ''O. virilis''.〔(【引用サイトリンク】work=Montana Field Guide )〕
