Throughout much of its distribution in North America, Schmidtea polychroa feeds primarily on oligochaetes. However, in Toronto Harbour, Ontario, Schmidtea polychroa and Dugesia tigrina are found to coexist; the latter is found at lower densities at each locality, suggesting potential intra-specific competition between the triclads.
