• Daphnia galeata

  water flea

  Daphnia galeata is a small planktonic crustacean inhabiting freshwater lakes across the Northern Hemisphere. The species exhibits pronounced phenotypic plasticity in response to environmental conditions, particularly food availability and predation risk. Two subspecies are recognized: D. g. galeata in the Old World and D. g. mendotae in North America, with hybrid populations occurring in the lower Great Lakes. It serves as a key model organism for studying predator-induced defenses and life-history evolution in aquatic systems.
