From deep-sea trenches to your home garden, gastropods (snails and slugs) are among the most diverse and successful groups of animal life in Earth history. This episode, we’ll explore what makes these animals distinctive, we’ll touch on their extraordinary fossil record, and we’ll investigate the many evolutionary experiments gastropods have undergone in their anatomy and lifestyle.

In the news: squishable ants, false saber-tooths, bee burrows, and baby ankylosaurs
