The third episode of the SquaMates podcast—bigger, better, and much, much longer than ever before! The show is rife with bad puns and brilliant science, and hosted by Mark D. Scherz, Gabriel Ugueto, and Ethan Kocak!
In this third episode, an unplanned drinking game is introduced, as well as a new section title! We talk about cobras, leafblowers, synapomorphic skull loss among stem Serpentes, and the ridiculous diversity of the Gymnophthghshmhalmidae, before diving into our main topic (by popular demand): the Toxicofera, and the age-old question, ‘just what is venom, anyway?’ and ‘why is my hand falling off?’ The featured #HERpers are a trifecta of amazing Victorian-Edwardian women, whose fates differed dramatically, but who helped light the way for women in herpetology.
