Rusty Crayfish Images

Rusty crayfish (Orconectes rusticus) have invaded much of Minnesota, Wisconsin, Michigan, Illinois, Ontario, and portions of 17 other states (http://nas.er.usgs.gov/). Although native to the Ohio River basin and the states of Ohio and Kentucky, rusty crayfish continue to spread into many lakes and streams where they cause a variety of ecological problems.

Feel free to use these images, however, please credit Jeff Gunderson, Minnesota Sea Grant.
