While this is an interesting story, I find it just as interesting that the scientists who first contemplated the study...were contemplating it while drinking beer! 
Barnacles can radically change the size and shape of their penises to fight the waves and have sex.
Here is the challenge for the tiny hard bodies: Barnacles want to mate but are permanently bound to whatever rock or hull they once latched onto.
Given that, they have evolved the longest penises of any creature for their size up to eight times their body length to seek out and have sex with their neighbors. (Most barnacles are hermaphrodites that alternate between male and female sexes over time.)
~snip~ (Hated to use this when discussing penises, but...)
"Over beers, we thought maybe barnacles could change the size and shape of their penises as well," Neufeld told LiveScience.
