Spiny waterflea is an invasive zooplankton (tiny organisms that travel by wind and water currents) that originated from Eurasia. Why should we care about invasive species? A species profile for Spiny Water Flea. “Spiny Waterflea (Bythotrephes Longimanus).” Minnesota Department of Natural Resources.
