Have you ever seen hundreds of fish moving together like one big group? It looks amazing—but there’s a smart reason behind it.
Introduction
Many fish swim together in groups called schools. This behavior is very common in the ocean and rivers. But why do fish do this?
What Is a School of Fish?
A school is a group of fish swimming in the same direction at the same time.
👉 They move together like a team.
Why Do Fish Swim in Groups?
1. Protection from Predators
Swimming in a group makes it harder for predators to catch one fish.
👉 More fish = less chance of being caught.
2. Easier to Find Food
Fish in groups can find food faster.
3. Save Energy
Swimming together helps reduce water resistance.
👉 This means fish use less energy.
4. Better Communication
Fish can quickly react to danger by following each other’s movement.
Some fish groups can move in perfect shape without crashing into each other.
Conclusion
Fish swim in groups to stay safe, find food, and save energy. It is a smart survival strategy used by many species.
