American River Crayfish Orconectes limosus


Orconectes limosus is a species of crayfish in the family Cambaridae. It is native to the east coast of North America, from Maine to the lower James River, Virginia, but has also been introduced to Europe. It is unusual in living in silty streams, rather than the clear water usually preferred by crayfish. Like Pacifastacus leniusculus, another invasive North American crayfish, O. limosus carries crayfish plague and is a threat to native crayfish.
