Fish Fake It Too
Brown trout reproduce externally — the male and female fish climax simultaneously and release their sperm and eggs into the open water. The event must be timed perfectly, so the female trout indicates she is about to release her eggs by digging a bed in the sand, crouching by it, opening her mouth and quivering. Male fish respond by crouching and quivering beside her. Their quivering intensifies and, about half the time, they both climax. The other half the time, the female quivers, but never releases her eggs.
That faking might serve the purpose of allowing female trout to save their eggs for higher-quality males, a theory supported by the observation that female trout were more likely to fake orgasms when better-looking, more dominant fish lurked nearby. More often, however, the females faked it when the males were not in the exact right position, says study author Erik Petersson, PhD, a biology professor at Uppsala University.
“What is the point of choosing a high quality male if you behave in such a way that your eggs will not be fertilized?” he says.
