"Beaver The beaver (genus Castor) is a large, primarily nocturnal, semiaquatic rodent. ""Castor"" includes two extant species, the North American beaver (""Castor canadensis"") (native to North America) and Eurasian beaver (""Castor fiber"") (Eurasia). Beavers are known for building dams, canals, and lodges (homes). They are the second-largest rodent in the world (after the capybara). Their colonies create one or more dams to provide still, deep water to protect against predators, and to float food and building material. The North American beaver population was once more than 60 million, but as of 1988 was 6–12 million. This population decline is the"
"Capybara The capybara (""Hydrochoerus hydrochaeris"") is a mammal native to South America. It is the largest living rodent in the world. Also called chigüire, chigüiro (in Venezuela) and carpincho, it is a member of the genus ""Hydrochoerus"", of which the only other extant member is the lesser capybara (""Hydrochoerus isthmius""). Its close relatives include guinea pigs and rock cavies, and it is more distantly related to the agouti, the chinchilla, and the coypu. The capybara inhabits savannas and dense forests and lives near bodies of water. It is a highly social species and can be found in groups as large"

"Hydrochoerus The genus Hydrochoerus contains two living and two extinct species of capybaras from South America, the Caribbean island of Grenada, and Panama. Capybaras are the largest living rodents in the world. The genus name is derived from the Greek ὕδωρ (""hýdor"", water) plus χοίρος (""choíros"", pig). Capybaras are semiaquatic, found in and near lakes, rivers, swamps, and flooded savanna. Their diets are dominated by grasses. Adults weigh up to . The gestation period is 130–150 days, with two to eight (most commonly four) young born to females. Capybaras are highly social, living in groups of up to 100 and"

"Neochoerus pinckneyi Neochoerus pinckneyi was a North American species of capybara. While capybaras originated in South America, formation of the Isthmus of Panama three million years ago allowed some of them to migrate north as part of the Great American Interchange. Capybaras and porcupines are the only caviomorph rodents that reached temperate North America during this exchange (a much greater diversity of North American rodents invaded South America). At 90 to 113 kg (200 to 250 pounds), 40% larger than the living capybara, ""N. pinckneyi"" is one of the largest rodent species ever discovered, surpassed only by the recently discovered"
