Guppies use ugly friends to seem more attractive
LONDON (AP) - When it comes to mating, guppies treasure their ugly friends - because they look so good by comparison.
An article published on Wednesday by Britain's Royal Society says that male guppies prefer to associate with their drab-coloured counterparts when females were around.
"Males actively choose the social context that maximises their relative attractiveness," the article said.
Or, as lead author Clelia Gasparini put it, "If you are surrounded by ugly friends, you look better."
