Discover the Hidden Story in a Slug’s Trail

Slugs are easy to miss, but their biology reveals a remarkable evolutionary story. In Slug Signals, Nora F. Mercer explores how these soft-bodied animals move, breathe, sense the world, and survive in places where moisture is precious and danger is constant.

  • What slug mucus is made of and why it matters
  • How slime reduces friction and helps slugs move
  • How mucus supports moisture control, defense, and signaling
  • What makes a slug a slug, and how slugs differ from snails
  • Why these humble animals illuminate ancient land life
