Scientifically termed Bertholletia excelsa, the Brazil nut tree is a tree that can be as tall as 160 feet, predominantly found in the Amazon rainforest in South America, and grown in the moist soil of the region. The tree relies on a specific kind of orchid bee for its reproductive process, making it unique.

The tree trunk is straight and smooth, and the top is covered with umbrella-like, large, shiny, and dark green-coloured leaves. The tree can age as old as 500 years and is known for its ability to produce large fruits similar to that of coconuts, but smaller in size. Inside each fruit, there are at most 10-25 Brazil nuts which are further enclosed in a spherical hard shell.

Apart from these characteristics, the tree also plays a key role in the ecosystem of the Amazon rainforest, providing shelter and food for various species. The nuts are important for creatures like squirrels and macaws. Communities native to the Amazon have depended upon Brazil nuts as a source of nutrition and income, as their harvest is sustainable. The growth of these trees is slow, causing problems related to deforestation, which is why conservation is crucial.
