During this episode, Steve talks about EVERY SINGLE extant non-human animal that drinks xylem or phloem sap. Join the guys as they explore the paradox of phloem sap, the barriers to eating it, how squirrels tap maple trees, hemipterans (true bugs), yellow-bellied sapsuckers, and much, much more. This episode stands alone, but we highly recommend listening to episode 17, "The Sappiest Podcast Ever..." either before or after this one. Either way, we hope you enjoy the episode!
