- Scientists studied how groups of birds and fish move.
- They watched groups that move together.
- The animals keep a similar spacing and order.
- The groups act like soft material with springs.
- This shape can bend and change easily.
- It reacts to air or water flow.
- Researchers used small flapping models in water.
- The model predicted how the group would behave.
- The model and tests showed the same patterns.
- A grant helped to pay for the study.
