Schools and schools of fish! Have you ever wondered why these fish run in packs? The adult readers probably already know the answer to this question. For the children, I will tell you... When fish travel together, it is called a school. Schools of fish exist for many reasons, and here are some of them:
1. They can confuse predators when they travel in schools by swimming back and forth.
2. There is safety in numbers. Large groups of fish mean that it is less likely for a single fish to be singled out and eaten.
3. They can travel on each others currents, which means they do not have to swim as hard to get where they need to go.
4. It is harder to find food on your own. A group of fish means that when one fish finds food, they all find food. However, the downside is that they would have to either share the food or fight to see who gets to it first.
We had a chance to see schools of fish at the aquarium. It was a pretty amazing sight watching them travel in a synchronized dance of sorts.
