The Capivara (Hydrochoerus hydrochaeris) is the largest living rodent in the world. Its common name, from “Kapiÿva” means “master of the grasses” in the Guarani indian language. Capivaras may grow to 130 centimetres in length, and weigh up to 65 kg. Capivaras reach sexual maturity within 22 months and breed when conditions are perfect, as they are semi-aquatic mammals found wild in lakes, rivers, swamps, ponds and marshes, as well as flooded savannah and along rivers in Cerrado, Amazon, Pantanal, Atlantic Forest and Pampas biomes.
