Cruising

The Wallace Line, separates the eco zones of Asia and Australia and runs through Indonesia, between Borneo and Sulawesi (Celebes), and through the Lombok Strait between Bali and Lombok. The distance between Bali and Lombok is small, about 35km (22 miles) but Wallace found a clear and striking division between organisms to the west (related to Asiatic species) and to the east of the line (species of Asian and Australian origin).
