Fish tend to school in giant balls for various reasons, such as protection from predators, improved foraging opportunities, and communication within the group. Schooling behavior allows fish to confuse predators by appearing as a larger, more intimidating group. This safety in numbers approach also enables fish to efficiently find food and navigate their environment. Furthermore, schooling fish are able to quickly communicate with each other through coordinated movements, enhancing their ability to work together and survive in their underwater world. These synchronized movements also play a role in the collective decision-making process within the group. Overall, the phenomenon of fish schooling in giant balls serves as a survival strategy that benefits individual fish as well as the group as a whole. It allows them to thrive in their natural habitat and increases their chances of survival in the face of various threats.
