- A cluster of oat flakes: the food source at the end of the maze.
- A thick yellow vein: the main route linking the starting area to the food.
- Thin yellow filaments: exploratory branches that withdraw from dead ends.
- A glossy wet film: the mucus trail left on the floor along the used route.
Examples
- A slime mold on a damp log grows toward a nearby fallen fruit.
- A snail trail on a sidewalk stays shiny and wet.
Key takeaways
- A slime mold can find the shortest route to food without a brain.
- It leaves mucus trails and pulls back branches that do not lead to food.
