What's the Difference Between a Phone Box and a Prostitute?

Female rough periwinkles can change the composition of their slime and basically turn on a cloaking mode where to hide their parasites. They leave well to hide the sex they leave a sex neutral trail because they've got so many bloody male rough periwinks chasing after them really not interested. If you look at how microorganisms are distributed in the sea or like plankton or tiny things they're not evenly distributed or randomly distributed they're sort of in clusters as I guess some bits are thicker than others in this weird cobweb.
