The crew speaks with Octopus researcher Dr. Eduardo Sampaio. Eduardo got his PhD studying octopus behavior, cognition, and social contexts and is a Nat Geo Explorer. Eduardo and his team studied octopuses in interspecies hunting parties that included eels and fish. The party is hunting when all of the sudden, one of the fishes gets smacked by the octopus. Eduardo walks us through what we currently think about the Cephalopunch.
