Why do fish travel in schools?
Published in Daily Trivia
Fish travel in schools for protection (a large school of fish may be ignored by predators looking for a lone straggler) and also for feeding (mackerel, for instance, hunt together). All the fish in a school of fish are not related to one another but are often (but not always) the same species. Fish in a school may be of different species, but they are usually the same size (much like the students in a human school hang out with kids their own size). Larger and smaller fish break away to form their own schools.
