A Louisiana-French word originally from the Choctaw "bayuk", a "small stream".
A bayou is a swampy area of slow-moving water inhabited by shrubs and trees like gum, bald cypress, or oak.
Animal species include reptiles such as the American alligator, frogs, snakes, turtles, and salamanders.
Most bayous are found in the southern Mississippi River bottomlands and several southeastern U.S. states bordering the Gulf Of Mexico.
If it moves, and you're in a bayou when you see it, you may be lunch. Unless you can swamp-walk real good.
