Capybara: Hydrochaeridae

Physical Characteristics, Diet, Behavior And Reproduction, Capybaras And PeopleGEOGRAPHIC RANGE, HABITAT, CONSERVATION STATUS

Capybaras are found on the eastern side of the Canal Zone in Panama, and on the east side of the Andes Mountains in South America, including Peru, Colombia, Venezuela, French Guiana, Guyana, Uruguay, Paraguay, Bolivia, Ecuador, Brazil, and northeastern Argentina.

Capybaras live in areas of dense trees and plants near rivers, streams, lakes, ponds, marshes, and swamps. There are four areas in South America where there are large concentrations of capybaras: the llanos (plains) in Venezuela, the Pantanal wetlands in western Brazil, the Taim lowlands in southern Brazil, and Marajó Island, at the mouth of the Amazon River in northeastern Brazil.

The capybara is not currently threatened, according to the IUCN. Hunting and exterminations by humans have caused populations to decline in some areas, particularly Venezuela and Peru, while they remain stable in others. However, some conservationists say the overall numbers are in decline.
