Tiny Testes

Headline of the week goes to:

Horniest male beetles have tiniest testicles
“Dung beetle research may be about to boost the cliché about men with flashy sports cars. According to new study, male beetles with the most dramatic and ostentatious sets of horns apparently pay for that with smaller testicles.  The research is one of the first studies to experimentally demonstrate that investing energy in one mating advantage may come at the expense of another.”
