The Amazon River carries a greater volume of water than any other river in the world and is about 4,000 miles (6,400 kilometres) long. The Amazon enters the Atlantic through a wide estuary, known as the Amazon Delta and estimated at 240 km (about 150 miles) in width. A maze of islands separate the river into branches and its main stream (the Para) is 80 km (50 miles) wide and is separated from the rest of the entrance channels by the huge Marajo Island (the size of Denmark). The port city of Belem is located on the southern side of the Delta while Macapa is the port on the northern channel. The river and its tributaries help support a rain forest ecology that contains more species of flora and fauna than any other ecosystem.
