SciShow: This Worm's Gut Has No Way In or Out

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: There are plenty of creatures out there with only one opening to handle both taking in food and getting rid of waste. But there’s at least one animal out there that doesn’t have a gut opening… at all. How does that even work?! Hosted by: Hank Green SciShow has a spinoff podcast! It's called SciShow Tangents.
