The Rio De La Plata is an estuary made from the confluence of three rivers: the Paraná, the Paraguay, and the Uruguay. Sebastion Cabot began a detailed study of the area in 1526. The few silver trinkets he obtained in barter with the Guarani people helped to establish the name of the estuary as the “River Of Silver.”

Lystrophis dorbignyi - The South American hognose snake has a distinctive upturned snout used for burrowing into leaf litter as a means of escape or when searching for food. The South American hognose snake is a timid snake. It relies on two defensive traits when threatened; it will rear up and hiss while spreading a false hood to resemble a cobra or it may play dead by rolling over on its back. The color of the hognosed snake is similar to the poisonous coral snake, serving as another form of protection.
