Why Do Fish School?

The video explores the fascinating behavior of schooling fish, highlighting how they coordinate movements without a leader. It distinguishes between schools and shoals, explaining their benefits beyond predator avoidance, such as reduced metabolic rates and increased growth. The video delves into the role of psychology, physics, and fluid dynamics in schooling, showing how fish save energy. A 2020 study using robotic fish reveals how fish adjust tail beats to optimize energy use, demonstrating the advantages of schooling even without predators.

What is one of the main benefits of fish forming schools or shoals?

• They reduce their chances of being eaten.

• They have a leader to guide them.

• They can swim faster individually.

• They can change color more easily.

How do schools and shoals help fish in terms of energy?

• They increase the fish's metabolic rate.

• They allow fish to use less energy daily.

• They make fish swim in a straight line.

• They help fish find food faster.

Why is it difficult for predators to target fish in schools?

• Fish in schools are invisible to predators.

• The mass of fins and tails confuses predators.

• Predators are afraid of large groups.

• Fish in schools swim too fast for predators.

What was the purpose of using robotic fish in the 2020 study?

• To create new types of fish.

• To scare away predators.

• To measure the swimming patterns and energy use.

• To teach fish how to swim in schools.

How do fish save energy when swimming in schools according to the study?

• By swimming faster than usual.

• By swimming in a straight line.

• By beating their tails in sync with each other.

• By adjusting their tail beats based on their position.
