C. elegans, one of the simplest known animals, has hermaphrodites and males, with hermaphrodites massively outnumbering the males.

Perhaps being male is a strategy to make others bear your offspring, while you don't have to, and after a certain proportion of males in the population emerges, you might as well be female instead of hermaphroditic?
