Ant Ground Vibrations
Open to everyone until Monday, September 28
To keep it, print it while it is open.
Some ants send signals by striking the ground or rubbing body parts, creating vibrations. Nearby nestmates feel these vibrations through their legs.
In the picture
- An ant’s lowered head on the soil: the point where a strike sends vibrations into the ground
- Concentric soil ripples: the spreading vibration in the ground
- A second ant’s legs: contact points that pick up the vibrating surface
- The soil surface between the ants: the medium that carries the vibration
Examples
- A worker ant taps the ground near a food source, and nearby nestmates respond.
- An ant rubs its body against a leaf, and a nestmate on the same leaf feels the tremor through its legs.
Key takeaways
- Ants can communicate without sound through ground vibrations.
- Legs are the main body parts that detect these vibrations.
