Abstract: An enclosure to provide aquatic, amphibious and terrestrial plants and animals and flying animals with a natural environment that prevents escape. In one embodiment, an aquatic area and terrestrial area are connected by way of two ramps, so that animals may go back and forth between water and land. The aquatic and terrestrial areas are able to be drained through bottom outlets. The upper part of the enclosure confines an air zone in which flying animals may fly above and land in the water and land zones. The upper part of the enclosure has side and top openings covered by panels. At least one of the side panels is openable. In the preferred embodiment, the panels are covered with screen, however, they may be covered with glass or plastic.
