Below you will find just a handful of our photos of aquatic invasive species. View our Flickr page for all photos we currently have available. If you are attempting to identify a species, we recommend you take a look at our AIS Identification Guidebook. The Guidebook has tips for identifying invasive species and also shows common Minnesota native look-alikes.

If you are looking for specific photos or are hoping to use or our photos in a publication, please reach out to us at [email protected]. Thank you!
