A partial differential equation which describes the dynamics of a single species population for animals reproducing by fission is set forth. The equation is then applied to Dugesia tigrina. Whenever possible, experimental results are used to determine pertinent parameters. Tests are performed to determine those parameters upon which the model has a critical dependence. The model gives results which are qualitatively in agreement with empirical populations.
