Education and outreach are a big part of what we do. We tell people not to swim at dusk and dawn, when sharks are most active, and definitely not at night. (That midnight swim might be romantic, but it could be your last.) We know that you should avoid swimming where people are fishing, or where you can see fish schooling or seabirds feeding, which could mean sharks are feeding, too. We also advise against wearing bright, shiny jewelry into the water, which sharks can confuse for the flashing of fish scales.
