Science writer, educator, and artist Dr. Danna Staaf recently published her first book, Squid Empire: The Rise and Fall of the Cephalopods, and she joins Matt and Andy to talk about her dissertation on the reproduction and early life of Humboldt squid, penis fencing among hermaphroditic flatworms, the fact that calamari pre-date the dinosaurs, and why we should all have a lot more respect and awe for cephalopods in general.
