Warabis inhabit and develop on land, outside of bodies of water, and their young develop in a pouch or mouth of the parent on land. The female carries the offspring in a pouch or mouth on land. A warabi’s embryo develops for one month, and the female gives birth to one tiny offspring after a short pregnancy. The offspring immediately moves into a pouch and remains there for several months. The species reaches maturity from 1 year to 1 year and 10 months. The reproductive interval is from 6 months and 3 weeks to 1 year and 1 month. Eggs or young develop in a nest built on or close to the ground, and nests are found inside tree trunks or in caves/crevices. Only the mother exhibits parental care within these nests located inside tree trunks or in caves/crevices. Nests can also be found in tree hollows and caves.
