Here are a few unique plants in South America. The Brazilian nut tree towers above many other trees in the Amazon rain forest, reaching over 160 feet when healthy. It is known for its producing of Brazilian nuts. Reaching as high as 130 feet, the rubber tree (or rubberwood tree) is known for its milky sap or commonly called latex. And yes, it is used to make rubber.
other Unique animals:
Here are some animals that are found in SA. Yes I said it, SA (South America). The Anaconda is a snake that is very deadly. They don’t attack humans, and despite being non-venomous, they're very powerful. If they wanted, a medium sized one could devour a human adult. They are indeed in the boa family, and are located throughout SA. Poison frogs have all sorts of beautiful color combinations. Big animals see them from a mile away, but if they try to eat them. Well, poison.
