Abstract
Unlike other vertebrates, a large number of teleost fishes are normal, functional hermaphrodites. In some of these, the male and female elements function at the same time; in others, there is transformation from one sex to the other. Simple mathematical models make possible comparison of the reproductive potentials that can be realized under the conditions of gonochorism and different types of hermaphroditism. These models suggest that life-span and degree of polygamy are critical factors in the evolution of hermaphroditism and that populations of metagonous (transforming) hermaphrodites in which individuals transform at different ages function like populations in which the sexes are separate.
