>>1266864On land, a gator will whip it's tail and try to sweep you off your feet if you get too close. However, that's very rare. Usually they won't stray from the water and you shouldn't fear them on land unless it's mating season (spring time) or it's a female protecting her eggs.
Gators hunt at night. Never go in water after dark. The sound of your splashing will draw gators to you and they are extremely fast and agile in the water.
From underwater, a person's silhouette is indistinguishable from animals that gators prey on. Gators feed at dawn and dusk, so you want to avoid shorelines and riverbanks at that time. pic very related
