The reproductive methods employed by freshwater triclads are briefly reviewed, and the origins and success of asexual reproduction in the Dugesiidae and Planariidae discussed. Evidence is presented to show that reproduction and environment are linked, and it is proposed that asexual reproduction can only persist in environments where biotic stress is low.
