What are schools in fish behavior?

• A. A group of fish that swim together but may not be as coordinated as schools.
• B. Flocks of birds.
• C. Schools are groups of fish that swim together in a coordinated manner for protection and social interaction.
• D. Unrelated individuals that pair up to breed.

Answer: (C)

In fish behavior, schooling refers to a group of fish that swim together in a highly coordinated, synchronized way for protection and social interaction. The description that emphasizes a coordinated, social, protective swimming pattern matches this idea, because schooling involves aligning with neighbors, staying close, and moving as one unit. This tight coordination helps confuse predators, increases vigilance, and can make for easier foraging as a group.

Think of it as the difference between a casual shoal—fish simply swimming together without tight, synchronized movement—and a true school, where the entire group moves in near-unison. The other option describes a group of fish that aren’t coordinated, which is more like a shoal, and the last option talks about mating pairs, not schooling.
