Purdue Grubbers: A New Breed of Invasive Species The American crayfish, also known as the signal crayfish or colloquially, the "Purdue grubber," has become a ubiquitous presence in the Great Lakes region.
Native to the southeastern United States, this invasive species was introduced to Lake Erie in the early 20th century and has since spread throughout surrounding waters.
The Purdue grubber's voracious appetite and reproductive prowess have made it a nightmare for local ecosystems, disrupting native habitats and posing a significant threat to native aquatic life.
