Why do we have snot? Do animals get stuffy noses, too? We delve into the world of thick secretions with the help of Dani Rabiaotti, zoologist and author of “Believe it or Snot: The Definitive Field Guide to Earth’s Slimy Creatures.” You’ll find out why we make so much mucus, and meet the slimiest animals on the planet. Plus, you’ll discover why scientists study slime, even though it’s super gross.

This is a rebroadcast of one of our favorite episodes from season 5, inspired by a question we recently got from our listener Harrison, who wondered why snot exists. Hopefully this answers the question for him!
