Barnacles Have Big, Bendy Penises

While the Tuberous Bushcricket may have the biggest balls relative to body weight in the animal kingdom, the barnacle comes out the winner in the largest penis competition. “According to new research published in Marine Biology, the shape of barnacles’ penises varies depending on their circumstances. Barnacles spaced far apart from each other develop stretchier organs, the better for reaching across the gaps, and barnacles exposed to rough waves grow wider ones to stand up against the tide.” Some barnacles also develop stretchy, foldy penises, “like an accordion or a bendy straw.” Now you know! (Above, barnacles do sex to each other.)
