Across the animal kingdom males harass females for mating opportunities.
This harassment is costly for females, in some cases reducing reproductive success and increasing mortality.
We report an extreme strategy for avoiding sexual harassment used by a species of small fresh water fish, the Trinidadian guppy Poecilia reticulata.
Females actively select areas of high predation risk, but low male presence, thus risking their lives to avoid sexual harassment and driving sexual segregation in the species.

posted by Christina Maris on 7 Aug 2008 at 11:17 amThe final line of this article - that it is the females' behavior that drives sexual separation - is misleading. Its is the constant harassment of females by males that leads to sexual separation. No ofemale, of any species, wants to be constantly "hit on" - something the males of nearly every species, including our own, seem to be slow in understanding. If a female can't get the male to stop, then the only thing she CAN do is remove herself from him.
Let's make sure we get the sequence correct as to who started it and who is making the best of it.
