Tropical rainforests are rainforests generally found near the equator. They are common in Asia, Africa, South America, Central America, and on many of the Pacific Islands. Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year.
The Amazon Rainforest is a moist broadleaf forest in the Amazon Basin of South America,  which encompasses seven million square kilometers (1.7 billion acres), though the forest itself occupies some 5.5 million square kilometers (1.4 billion acres), located within nine nations: Brazil, Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana.

The Amazon represents over half of the planet's remaining rain forests and comprises the largest and most species-rich tract of tropical rainforest in the world and have unparalleled biodiversity.

The region is home to about 2.5 million insect species, tens of thousands of plants, and some 2000 birds and mammals. To date, at least 40,000 plant species, 3,000 fish, 1,294 birds (one in five of all the birds in the world live in the rainforests of the Amazon), 427 mammals, 428 amphibians, and 378 reptiles have been scientifically classified in the region,  with many more remaining to be discovered or catalogued.
