A litter has 2 to 4 individuals, and the young reach maturity from 3 to 5 years of age. The species inhabits and develops on land, outside of bodies of water, with nests located directly on the surface of the ground, where eggs or young develop. The nest is situated directly on the surface of the ground on land, and only the mother exhibits parental care. The interval between reproduction is from 2 to 3 years.
