NOAA Great lakes Environmental Research Laboratory (GLERL) has complied a database of over 180 aquatic non-indigenous plants and animals that are present, expanding their ranges within, or predicted to invade the Great Lakes basin. Each species listed in this Great Lakes Aquatic Nonindigenous Species Information System (GLANSIS) can be searched by common name, scientific name, or taxonomic group, and has its own associated page detailing its unique identifiers, country of origin, and where is has been located in the Great Lakes basin to date.
