Are you hungry for braaaaiiiinnnnssss? Or for fugu at the very least? We hope so, because this week we’re talking zombies and tetrodotoxin. In this crossover episode with Dr. Shane Campbell-Staton from The Biology of Superheroes Podcast, we trace the origin of the modern pop culture zombie back to its Haitian roots. We explore the outrageous evolutionary arms races in which tetrodotoxin, the principal component of so-called ‘zombie powder’, has played a major part. And finally, we answer the age-old question: can a pufferfish make you into a zombie? Be sure to check out Part 1 of this crossover episode, Episode 7 of The Biology of Superheroes Podcast, where we discuss the biological basis of death, whether we’re prepared for a zombie outbreak, and behavior-manipulating parasites.
