Female guppies risk their lives to avoid too much male attention

Sexual harassment is a burden that females of many species face, and some may go to extreme lengths to avoid it.

In a new paper from the June issue of the American Naturalist, Darren Croft (University of Wales) and a research team from the University of Leeds suggest that female guppies, a popular aquarium fish, may risk their lives to avoid too much attention from males. Observing wild population of guppies in the rainforest of Trinidad, the researchers found that female guppies swim in habitats that contain few males ?but many predators.

"Male guppies spend most of their time displaying to females. But if their courtship displays don't impress the females, males will attempt to sneak mating with them when they aren't looking," says Croft.

Male guppies are brightly colored to attract female attention, while female guppies are a dull brown color. The researchers show that female guppies might use this color difference to their advantage, venturing into the deep water where predators lurk. The males' bright coloring also attracts predators, making it too dangerous for them to follow.

"Understanding why and how [sexual segregation] occurs is essential if we are going to conserve and protect species and habitats," explains Croft, who points out that fish are not the only species who display this social characteristic. "In many ecosystems, predators are the first to go extinct, and our work shows that this may have many, perhaps unexpected, effects. In this case, females may suffer more sexual harassment."
