Red Swamp Crayfish

Jul 24, 2019 | Latest News

The red swamp crayfish has been detected in Michigan. Red swamp crayfish behave aggressively for food and habitat. This aggressive behavior also affects native amphibians, invertebrates, and fish by reducing their available habitat. In addition, their behavior can lead to cyanobacteria blooms.

They grow up to 5 inches, have dark red bodies and claws, and have a black wedge-shaped stripe on their underside.
