In Louisiana, the so-called bayous form a network of navigable water arms with marshy banks that stretches for thousands of kilometers . The waters flow very slowly, with a barely noticeable current towards the sea at low tide and upstream at high tide. This complex ecosystem is home to a great diversity of animal and plant species.

It documents the sometimes surprising behavior of numerous animals that live there, such as ants, raccoons, crayfish, water turtles, egrets, pelicans, fish and jellyfish. The Mississippi alligator also lives here, growing up to two and a half meters long and weighing in at 90 kilograms.
