They can be found in many areas in zoos and parks[22] and may live for 12 years in captivity. Revista Brasileira de Zoologia. Capybaras are known to be gregarious. Group living appears to be extremely important to capybara survival—without a group, an individual is excluded from most grazing habitat and has no chance of finding a mate, so solitary capybaras are seldom found.

Animals portal Latin America portal. Retrieved 8 June Hydrochoerus hydrochaeris English names: Despite these threats, the species still has a wide distribution and large global population 1and the increasing conversion of forest to grassland, together hyydrochoerus management regimes employed on cattle ranches such as predator control, provision of water, and burningmay even be helping to create more suitable capybara habitat 5 9.


Capybaras sometimes raid gardens or farms in search of food, such as melons, squashes, or grains. Mammalian Species Their hide was once traded in Argentina which caused the death of more than 80, of them.
