110: Marine Flatworm

Who doesn't love a worm? Particular a very small, very wet, very fragile one? This week, we investigate a tiny ocean man and get all up in his business. Whip out those microscopes and take a peep at this paper-thin pal. Join us and learn answers to your burning questions, like: how'd he get so thin? What's up with his butt, or lack thereof? How is he different from nudibranchs and sea slugs? Why ON EARTH does he have two penises? And why is penis fencing now a part of my search history?
