Animals of the Amazon River Basin

By

The Amazon rainforest is a moist broadleaf forest that blankets 5,400,000 square kilometers of the Amazon River basin in South America. The shear vastness of this forest is difficult to comprehend. It stretches across the boundaries of nine nations—Brazil, Colombia, Peru, Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana. Its biodiversity is unparalleled—an estimated one in ten animals on the planet inhabits the Amazon rainforest. Listed here are a few of the better-known species from the Amazon rainforest and its surrounding habitats.

Capybars live in a variety of different habitats but prefer plces that are close to water such as flooded grasslands, lowland forests, rainforests, and marshes. The closest relatives to the capybaras are the guineapigs and rock cavies.
