  1. Open with a stunning, unusual invertebrate image (e.g., Glaucus atlanticus or Tardigrade).
  2. Integrate recent phylogeny (2020s molecular trees).
  3. Use the “assertion-evidence” slide structure – claim at top, visual evidence below, minimal text.
  4. End with a real research highlight (e.g., “How octopuses edit their RNA – 2023 study”).
  • Shape: Cylindrical, unsegmented worms with tapered ends.
