Darned scientists and the things they do in the name of science! Can't they leave a poor copepod doin' its bidnis alone?
The marine biologists on the Galathea expedition intruded on the privacy of this copepod - all in the name of science, mind you - as it ... went poo! Link [embedded YouTube clip]
Why do you come here if you're so easily offended? I'd hate to think of how you deal with your cat's litterbox... or your child's diapers. Everybody poops, you know (yes, even sea creatures).
Of course, the great and powerful AnUnSi never has to go to the bathroom. The waste just magically appears in the toilet bowl. "Immaculate bowel movements", if you will.
