Close to 80% of the world’s fish swim in schools at some stage during their life cycle. Swimming in schools helps to protect individual fish against predators, and makes swimming easier for individual fish.
Eastern hulafish (Trachinops taeniatus) are one example of schooling fish which you will find whilst snorkelling Mosman. These fish grow up to 10cm, and are easy to spot with their red and yellow stripe. They get their name from their unique swimming motion. Eastern Hulafish eat zooplankton and will be spotted around pylons and sheltered reefs.
