What are shoals?

What are shoals?

• A. A type of fish.
• B. Groups of fish that swim together but may not be as coordinated as schools.
• C. A single large predator.
• D. A seasonal migration pattern.

Answer: (B)

In animal behavior, shoals are groups of fish that swim together without forming a tightly coordinated unit. Members stay in the same general area and may join for protection or feeding, but each individual typically keeps its own speed and direction rather than moving as a single synchronized group.

This is why the best answer describes shoals as groups of fish that swim together but may not be as coordinated as schools. It captures the idea of a loose, collective presence without rigid, synchronized movement.

The other ideas aren’t accurate: a shoal is not a distinct species of fish, it’s not a single large predator, and it doesn’t refer to a seasonal migration pattern.
