Shoaling is a behavior where fish swim together in a large, coordinated group. This behavior offers several advantages, such as:
* Increased protection from predators: A large shoal can confuse predators and make it harder for them to target individual fish.
* Improved foraging efficiency: Shoals can work together to find food and increase the chances of finding it.
* Increased reproductive success: Shoaling can help fish find mates and raise their young.
While shoaling is most commonly associated with fish, other animals like birds, insects, and even mammals can also exhibit similar group behaviors.
