The Río de la Plata widens from about 2 kilometres (1.2 miles) at the inner part to about 220 km (140 mi) at its mouth.[7] Buenos Aires is on its western shore. Montevideo is on its northern shores.
The Río de la Plata is home for the loggerhead sea turtle, green sea turtle, leatherback sea turtle, the rare La Plata dolphin, and many species of fish.
Battle of the River Plate (1939) change
The first naval battle of the Second World War was fought near the River Plata. The Kriegsmarine "pocket battleship" Admiral Graf Spee was engaged by the Royal Navy cruisers, HMS Exeter, Ajax and Achilles off the estuary of the River Plate in December 1939.
The German ship retired up the estuary with a crippled fuel system and put into port at Montevideo. A few days later, rather than fight outgunned against the British, she was scuttled in the estuary. This engagement was part of the early Battle of the Atlantic skirmishes.
